You can find the proxy settings applicable to your machine and use them to set up Local Testing connections.
Introduction
A proxy server sits between your machine and your ISP. In most organizations, proxies are configured
by network admins to filter and/or monitor inbound and outbound web traffic from employee computers.
In this article, we’ll show you how to view proxy settings (if your computer is behind a proxy server).
You can then use the information to set up Local Testing connections with BrowserStack..
Find Proxy Settings in Windows
In most cases, browsers will use proxy settings that are set on the computer. However, each browser has a
settings page to configure proxy settings as well.
There are two ways to find proxy settings in Windows: via the Settings app (Windows 10 only) or via the
Control Panel.
Using the Settings App (Windows 10) to find proxy settings
Click on Start, then click on the gear icon (Settings) at the far left.
In the Windows Settings menu, click on Network & Internet.
In the left pane, click on Proxy.
Here you have all the settings that are related to setting up a proxy in Windows. It’s split into
two configurations: Automatic or Manual proxy setup.
Using the configuration details to set up Local Testing connection:
If “Use setup script“ is enabled, it means that you have configured PAC proxy on your system. You
can obtain the path to PAC file from the “Script Address“ section.
Note: To set up a Local Testing connection using the PAC file, you need to ensure that the PAC file is stored on your computer and path needs to an absolute path to that file.
If “Manual proxy setup” is enabled, you can simply obtain Proxy Host and Port from the “Address“
and “Port“ section.
For Local Testing to work correctly, you need to bypass the traffic for – – from your
proxy. You can do this by adding an entry in the Proxy Exception> text field in the
“Manual proxy setup” section.
Using Control Panel (all Windows versions) to find proxy settings
In any Windows version, you can find the proxy settings via the Control Panel on your computer.
Click on Start and open the Control Panel. Then click on
Internet Options.
In the Internet Options, go to Connections > LAN settings.
Here you have all the settings that are related to setting up a proxy in Windows. It’s basically
split into two configurations: either Automatic configuration or
Proxy Server setup.
If “Use automatic configuration script“ iis checked, it means that you have configured PAC proxy
in your system. You can obtain the path to PAC file from the “Script Address“ section.
If “Use a proxy server for your LAN” is checked, you can obtain Proxy Host and Port from the
“Address“ and “Port“ section.
proxy. You can do this by clicking the “Advanced“ button and adding an entry in the
“Do not use proxy server for addresses beginning with:“ text field.
Find Proxy Settings in OS X
On OS X, you have to view the proxy settings in System Preferences. This is where most browsers check automatically. However, each browser has a settings page to configure proxy settings as well.
Open System Preferences and click on Network.
On the left-hand side, click on an active network connection. Note that you can have different proxy settings for different network connections. Click on the Advanced button on the bottom right.
Click on the Proxies tab and you’ll see a list of proxy protocols you can configure.
If “Automatic Proxy Configuration“ is checked, it means that you have configured PAC proxy in your system. You can obtain the path to PAC file from the “Script Address“ section.
If “Web Proxy (HTTP)” or “Secure Web Proxy (HTTPS)“ is checked, you can simply obtain Proxy Host, Port, Username, and Password.
For Local Testing to work correctly, you need to bypass the traffic for – – from your proxy. You can do this by adding an entry in the ”Bypass proxy settings for these Hosts & Domains” text field.
Connection duration and disconnection
In Linux, finding your proxy settings will depend on what distribution you are running. Mostly, the procedure would be similar for the various distributions.
On Ubuntu, open on System Settings from the launcher and scroll down to Hardware. Click on Network.
Click on Network Proxy, you can choose from Automatic or Manual.
If the “Automatic“ option is selected, it means that you have configured PAC proxy in your system. You can obtain the path to PAC file from the “Configuration URL“ section.
If the “Manual“ option is selected, you can simply obtain Proxy Host and Port from the appropriate section.
For Local Testing to work correctly, you need to bypass the traffic for – – from your proxy. You can do this by using the command-line interface as follows:
To change proxy exceptions, use ‘set’ option with ‘gsettings’ command as follows.
$ gsettings set ignore-hosts “[‘localhost’, ”, ‘::1’]”
If access to the above sections is restricted on your computer, you can seek help from your IT/Network Team to gather this information.
Windows could not automatically detect network proxy settings

Windows could not automatically detect network proxy settings

After having Windows troubleshoot a network error for you, you might have come across this message:
Windows could not automatically detect this network’s proxy settings.
What does this mean, and how do you fix it? Let’s take a look at Windows’ proxy settings and the steps to repair this.
1. Reboot Your Computer and Router
Before you launch into advanced troubleshooting, it’s always a good idea to restart your equipment first. There’s a chance that this will clear up your issue in a few moments.
Because this error is usually related to misconfigured settings on one computer, restarting your router likely won’t have an effect. But it’s still worth a try whenever you run into network problems of any kind.
If, after you reboot your computer and router, the problem hasn’t fixed itself, continue on with the more detailed steps.
2. Review Proxy Settings in Windows
Because this issue is related to your Windows proxy settings, that’s a sensible first place to check. To access proxy settings in Windows 10, open Settings, select the Network & Internet category, and switch to the Proxy tab on the left sidebar.
Here you’ll see a list of options related to proxy servers. If you don’t use a proxy (as is the case for most home users), make sure that Use a proxy server near the bottom is turned off. Leave Automatically detect settings on if it is already.
For users who do connect with a proxy, such as in a business or school environment, you might want to check with your system administrator to make sure you have the correct proxy details here.
After this, try reconnecting to the network again. If you still get the error, turn off Automatically detect settings in the proxy options and try once more.
What’s a Proxy Server?
We don’t want to bore you with the details while you try to fix this proxy setting issue. However, it’s useful to understand the basics of what a proxy actually is, and why Windows can run into problems with it.
Essentially, a proxy server acts as a middleman between your computer and the internet. Instead of you connecting directly to the internet, you connect to the server, which grabs information from the internet for you.
These are most common in business and school use, where system administrators use them for security and efficiency. It’s very unlikely that you would use a proxy server on your home network, unless you specifically set one up. This is why you should clear any proxy settings that might exist when you run into this issue.
3. Run the Network Adapter Troubleshooter
When you right-click on the network connection icon in your System Tray and choose to troubleshoot, it runs the Internet Connections troubleshooter. This is what results in the “Windows could not detect proxy settings” error. But there’s another network troubleshooter you can run that might provide more help.
Open Settings again and visit Update & Security > Troubleshoot. Click Additional troubleshooters, then choose Network Adapter from the list and walk through the troubleshooter. As seasoned Windows users know, these troubleshooters don’t always fix your problem, but it’s still worth a try.
4. Auto-Obtain IP Address and DNS Info
As it turns out, there aren’t many troubleshooting steps specific to proxy servers. We’ll share more tips below, but bear in mind that the troubleshooting looks similar to fixing the “No Internet Access” Windows error from this point on.
While not technically related to your proxy settings, misconfigured IP address or DNS settings can cause this error too. To check these, browse to Settings > Network & Internet > Status. Click the Change adapter options button in the list to see all your network connections, then double-click on the one you’re using.
Here, click the Properties button and double-click Internet Protocol Version 4 in the list. Make sure you have both Obtain an IP address automatically and Obtain DNS server address automatically selected. Misconfigured settings here will prevent you from getting online.
5. Update or Roll Back Your Network Driver
An outdated network driver may lead to connection problems. Similarly, you might have recently installed a botched update for your network driver. In either case, replacing the driver could clear the proxy message issue.
Right-click on the Start button and choose Device Manager to open this utility. Expand the Network adapters section and double-click on the connection you use.
Then, on the Driver tab, you can choose Roll Back Driver to uninstall the latest update and return to the previous one. Use this if you started experiencing this issue after updating—it might not be available in all cases.
Choose Update Driver and you can check for new updates over the internet. This likely won’t find anything though, so you’ll need to manually update your drivers by downloading them from the manufacturer.
6. Reset Network Configuration via the Command Prompt
Windows offers many network troubleshooting tools through the Command Prompt. A few quick commands can often clear up your issue in moments. If you’re still having trouble at this point, right-click the Start button again and open a Command Prompt (or PowerShell) with administrator rights.
Then run the following commands, one at a time. They will reset various network functions of your computer, such as clearing out old connection data and getting a new IP address from the router:
netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
7. Review Firewall, VPN, and Antivirus Software
You should next make sure you don’t have a firewall, VPN, or security suite interfering with your network connection. Perhaps your chosen software had an update that changed an option you weren’t aware of, or you just installed a new app that changed proxy settings for some reason.
Try disabling your firewall, VPN, and antivirus software one at a time, then see if the error goes away. If it does, the issue lies with one of those apps. You’ll need to configure them to avoid interfering with regular network activity.
8. Scan for Malware
Some malware can continually mess with your proxy settings to prevent you from getting online. If you run into the “Windows could not detect this network’s proxy settings” message every time you reboot, you may be a victim of this.
You should thus run a scan with a trusted anti-malware app, like Malwarebytes. This will detect any malware running on your system and get rid of it. If the scan finds any infections, take the recommended action and see if your connection works as normal again.
9. Utilize a Restore Point
The System Restore feature in Windows lets you return to a previous point when your computer was working normally. If your issues started recently, you should try this to see if you can go back in time.
To access it, head to Settings > System > About. On the right sidebar there, click System protection (expand the Settings window horizontally if you don’t see it).
In the resulting System Properties dialog box on the System Protection tab, click System Restore to open a new window. Windows will walk you through choosing a restore point and confirming the operation. Of course, if your computer hasn’t created any restore points, you can’t use this feature.
Note that using a restore point will remove any programs and drivers you’ve installed since making that restore point. You can click Scan for affected programs on a restore point to see what effect it will have. A System Restore won’t affect any of your personal files.
10. Reset Your Network Settings
After trying everything above, you should resort to a full reset of your network configuration in Windows. You’ve already spent a lot of time working on this, and a reset should clear whatever persistent problem is blocking your connection with this “cannot detect proxy settings” error.
Thankfully, Windows 10 makes it easy to reset your whole configuration. Open Settings > Network & Internet. On the Status tab, find Network reset at the bottom and click it.
Be aware that this will remove all network information from your computer, so you’ll need to reconnect to saved networks again. If you’re OK with this, click Reset now. Your computer will perform the reset, then restart.
Windows Could Not Detect Proxy Settings, Resolved
Now you know what to do when Windows cannot detect proxy settings. All network errors are frustrating, but you should be able to clear this one up without much work. It’s most important to make sure that you have a proxy turned off (if you don’t use one) or configured properly (if you do use one).
Otherwise, some standard network troubleshooting should have you all patched up and ready to get back online.

What is a Proxy Server and How Does it Work? – Varonis

The actual nuts and bolts of how the internet works are not something people often stop to consider. The problem with that is the inherent danger of data security breaches and identity theft that come along with the cute dog pictures, 24-hour news updates, and great deals online.
But what actually happens when you browse the web? You might be using a proxy server at your office, on a Virtual Private Network (VPN) or you could be one of the more tech-savvy who always use a proxy server of some kind or another.

“It’s a new world of remote work and this was a jumpstart on securing it. ”
What’s a Proxy Server?
A proxy server is any machine that translates traffic between networks or protocols. It’s an intermediary server separating end-user clients from the destinations that they browse. Proxy servers provide varying levels of functionality, security, and privacy depending on your use case, needs, or company policy.
If you’re using a proxy server, traffic flows through the proxy server on its way to the address you requested. The request then comes back through that same proxy server (there are exceptions to this rule), and then the proxy server forwards the data received from the website to you.
If that’s all it does, why bother with a proxy server? Why not just go straight from to the website and back?
Modern proxy servers do much more than forward web requests, all in the name of data security and network performance. Proxy servers act as a firewall and web filter, provide shared network connections, and cache data to speed up common requests. A good proxy server keeps users and the internal network protected from the bad stuff that lives out in the wild internet. Lastly, proxy servers can provide a high level of privacy.
How Does a Proxy Server Operate?
Every computer on the internet needs to have a unique Internet Protocol (IP) Address. Think of this IP address as your computer’s street address. Just as the post office knows to deliver your mail to your street address, the internet knows how to send the correct data to the correct computer by the IP address.
A proxy server is basically a computer on the internet with its own IP address that your computer knows. When you send a web request, your request goes to the proxy server first. The proxy server then makes your web request on your behalf, collects the response from the web server, and forwards you the web page data so you can see the page in your browser.
When the proxy server forwards your web requests, it can make changes to the data you send and still get you the information that you expect to see. A proxy server can change your IP address, so the web server doesn’t know exactly where you are in the world. It can encrypt your data, so your data is unreadable in transit. And lastly, a proxy server can block access to certain web pages, based on IP address.
What are Forward Proxies
A forward proxy server sits between the client and an external network. It evaluates the outbound requests and takes action on them before relaying that request to the external resource.
Most proxy services that you’re likely to encounter are forward proxies. Virtual Private Networks and Web content filters are both examples of forward proxies.
What are Reverse Proxies
A reverse proxy server sits between a network and multiple other internal resources. A large website might have dozens of servers that collectively serve requests from a single domain. To accomplish that, client requests would resolve to a machine that would act as a load balancer. The load balancer would then proxy that traffic back to the individual servers.
Some popular open source reverse proxies are:
Varnish
Squid
Why Should You Use a Proxy Server?
There are several reasons organizations and individuals use a proxy server.
To control internet usage of employees and children: Organizations and parents set up proxy servers to control and monitor how their employees or kids use the internet. Most organizations don’t want you looking at specific websites on company time, and they can configure the proxy server to deny access to specific sites, instead redirecting you with a nice note asking you to refrain from looking at said sites on the company network. They can also monitor and log all web requests, so even though they might not block the site, they know how much time you spend cyberloafing.
Bandwidth savings and improved speeds: Organizations can also get better overall network performance with a good proxy server. Proxy servers can cache (save a copy of the website locally) popular websites – so when you ask for, the proxy server will check to see if it has the most recent copy of the site, and then send you the saved copy. What this means is that when hundreds of people hit at the same time from the same proxy server, the proxy server only sends one request to This saves bandwidth for the company and improves the network performance.
Privacy benefits: Individuals and organizations alike use proxy servers to browse the internet more privately. Some proxy servers will change the IP address and other identifying information the web request contains. This means the destination server doesn’t know who actually made the original request, which helps keeps your personal information and browsing habits more private.
Improved security: Proxy servers provide security benefits on top of the privacy benefits. You can configure your proxy server to encrypt your web requests to keep prying eyes from reading your transactions. You can also prevent known malware sites from any access through the proxy server. Additionally, organizations can couple their proxy server with a Virtual Private Network (VPN), so remote users always access the internet through the company proxy. A VPN is a direct connection to the company network that companies provide to external or remote users. By using a VPN, the company can control and verify that their users have access to the resources (email, internal data) they need, while also providing a secure connection for the user to protect the company data.
Get access to blocked resources: Proxy servers allow users to circumvent content restrictions imposed by companies or governments. Is the local sportsball team’s game blacked out online? Log into a proxy server on the other side of the country and watch from there. The proxy server makes it look like you are in California, but you actually live in North Carolina. Several governments around the world closely monitor and restrict access to the internet, and proxy servers offer their citizens access to an uncensored internet.
Now that you have an idea about why organizations and individuals use a proxy server, take a look at the risks below.
Proxy Server Risks
You do need to be cautious when you choose a proxy server: a few common risks can negate any of the potential benefits:
Free proxy server risks
You know the old saying “you get what you pay for? ” Well, using one of the many free proxy server services can be quite risky, even the services using ad-based revenue models.
Free usually means they aren’t investing heavily in backend hardware or encryption. You’ll likely see performance issues and potential data security issues. If you ever find a completely “free” proxy server, tread very carefully. Some of those are just looking to steal your credit card numbers.
Browsing history log
The proxy server has your original IP address and web request information possibly unencrypted, saved locally. Make sure to check if your proxy server logs and saves that data – and what kind of retention or law enforcement cooperation policies they follow.
If you expect to use a proxy server for privacy, but the vendor is just logging and selling your data you might not be receiving the expected value for the service.
No encryption
If you use a proxy server without encryption, you might as well not use a proxy server. No encryption means you are sending your requests as plain text. Anyone who is listening will be able to pull usernames and passwords and account information really easily. Make sure whatever proxy server you use provides full encryption capability.
Types of Proxy Servers
Not all proxy servers work the same way. It’s important to understand exactly what functionality you’re getting from the proxy server, and ensure that the proxy server meets your use case.
Transparent Proxy
A transparent proxy tells websites that it is a proxy server and it will still pass along your IP address, identifying you to the web server. Businesses, public libraries, and schools often use transparent proxies for content filtering: they’re easy to set up both client and server side.
Anonymous Proxy
An anonymous proxy will identify itself as a proxy, but it won’t pass your IP address to the website – this helps prevent identity theft and keep your browsing habits private. They can also prevent a website from serving you targeted marketing content based on your location. For example, if knows you live in Raleigh, NC, they will show you news stories they feel are relevant to Raleigh, NC. Browsing anonymously will prevent a website from using some ad targeting techniques, but is not a 100% guarantee.
Distorting proxy
A distorting proxy server passes along a false IP address for you while identifying itself as a proxy. This serves similar purposes as the anonymous proxy, but by passing a false IP address, you can appear to be from a different location to get around content restrictions.
High Anonymity proxy
High Anonymity proxy servers periodically change the IP address they present to the web server, making it very difficult to keep track of what traffic belongs to who. High anonymity proxies, like the TOR Network, is the most private and secure way to read the internet.
Proxy servers are a hot item in the news these days with the controversies around Net Neutrality and censorship. By removing net neutrality protections in the United States, Internet Service Providers (ISP) are now able to control your bandwidth and internet traffic. ISPs can potentially tell you what sites you can and cannot see. While there’s a great amount of uncertainty around what is going to happen with Net Neutrality, it’s possible that proxy servers will provide some ability to work around an ISPs restrictions.
Varonis analyzes data from proxy servers to protect you from data breaches and cyber attacks. The addition of proxy data gives more context to better analyze user behavior trends for abnormalities. You can get an alert on that suspicious activity with actionable intelligence to investigate and deal with the incident.
For example, a user accessing GDPR data might not be significant on its own. But if they access GDPR data and then try to upload it to an external website, it could be an exfiltration attempt and potential data breach. Without the context provided by file system monitoring, proxy monitoring, and Varonis threat models, you might see these events in a vacuum and not realize you need to prevent a data breach.
