Hello Charles,
Thank you for your reply.
I appreciate your efforts towards resolving the issue.
I would suggest you to run system file checker(SFC) as issue may occur due to
corrupt or missing Windows files.
Refer this article:
Use the System File Checker tool to repair missing or corrupted system files
System file checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files.
I hope it helps.

FIX: The Proxy Server Isn’t Responding –

“The proxy server isn’t responding”, followed by a probable cause of the error and a couple of tips on dealing with it, is an error message that is displayed when a user affected by it attempts to access the internet through an internet browser such as Internet Explorer, Google Chrome or Mozilla many cases, if an affected user has two or more browsers installed on their computer, they observe that one of their internet browsers works perfectly fine. The “Proxy server isn’t responding” error message indicates that the proxy server that a person is using is not responding to the requests their computer is sending to it, and this is alarming for many users affected by this issue because most of them don’t even use a proxy server to begin with! In most cases, the “Proxy server isn’t responding” error is simply caused by some kinks or issues with your registry and can be easily rectified. However, a suspicious or malicious program can also cause a harder to deal with version of this issue, which I will talk about later on. First things first, if you are seeing the “Proxy server isn’t responding” error every time you try to access the internet using a browser, go through the following steps in order to resolve the issue:Check Internet PropertiesHold the Windows Key and Press R. Type and Click OK. Go to the Connections tab, and choose LAN Settings. Make sure “Use a Proxy Server for your LAN” is unchecked. If it checked, uncheck it, click OK / Apply and done, reboot the PC and TEST. If it still won’t work, move to the Registry Editor Method Proxy Settings via Registry EditorIt is important to back up your registry settings before changing it. Hold the Windows Key and Press R. Type regedit in the run dialog and click OK. To backup registry, after opening it, Click File-> Export, name the registry file, eg: backupreg and click Save. To import / restore from backup, open registry editor again, click File -> Import, and select the file you exported earlier which is your back up. After it has been backed up; Navigate to the following path:Computer\HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet SettingsIn the right pane, locate the ProxyEnable string. Right Click on it and choose Delete. If there is a ProxyServer string, Migrate Proxy, and Proxy Override, right click on it and delete them as reboot the PC and TEST. If it still wont respond, then proceed with steps your web browsersIf you’re on Windows 10 and using Edge then follow steps here reset edge otherwise choose the tab for the browser you’re using.
Reset Internet Explorer
Reset Google Chrome
Reset Mozilla Firefox
Reset Microsoft Edge
To reset Internet Explorer; hold the windows key and press will open run dialog, in the run dialog type and go to the Advanced Tab; from the Advanced Tab; choose Reset, and put a check on Delete Personal Settings, then hit the reset button again. This will not delete your bookmarks BUT you will need to get them back by doing CTRL + SHIFT + B or by going to the bookmarks menu Resetting Google Chrome usually doesn’t proves fruitful so what i’d recommend is creating a new Chrome Profile. Before we do this; take a back up of your bookmarks so they can be imported later. See this guide for importing/exporting chrome Google Chrome the keyboard shortcut Windows key +R to open run the Run Dialog window that appears enter the following in the address dows Vista/ Windows 7/ Windows 8/ Windows 10/ Windows 10:%LOCALAPPDATA%\Google\Chrome\User Data\Locate the folder called “Default” in the directory window that opens and rename it as “Backup default. ”Try opening Google Chrome again. A new “Default” folder is automatically created as you start using the the Firefox’s address bar; type about:support and choose Refresh Firefox; then Refresh Firefox Here to view Steps on Resetting EdgeIf after resetting the browsers, it does start to work then this is most likely caused by a adware which must be removed in order to stop it from coming back. To do this, you can use AdwCleaner (google it) to download it and install it, and then clean the adwares. However, If it still shows proxy server isn’t responding error, then do a full scan using your antivirus software and remove any threats it finds, if it still won’t work, then uninstall antivirus/malware and vpn, or other security softwares temporarily to test. If it then works, you can put your security program back, doing this will reset the rules configured in the firewall/antivirus, check out Windows could not automatically detect this Network’s Proxy settings

Bypass proxy servers for web requests
Some network requests have to bypass the proxy. The most common reason is for local (intranet) addresses. Generally, these addresses don’t contain periods.
To bypass the proxy, select the Bypass proxy server for local (intranet) addresses check box in the Local Area Network (LAN) Settings dialog box. This method bypasses the proxy for all addresses that don’t contain a period (for example, compserv). These addresses will also be resolved directly.
To bypass more complex addresses, set up exceptions for specific addresses or wildcards by using either of the following procedures.
Use the browser settings
If you’re configuring proxy settings on a user’s computer after the deployment, follow these steps:
In Internet Explorer, open the Tools menu, and then select Internet Options.
On the Connections tab, select LAN Settings.
In the Local Area Network Settings dialog box, select the Use a proxy server for your LAN settings check box.
Select the Advanced tab, and enter the appropriate exceptions in the Do not use proxy server for addresses beginning with: box.
Multiple exceptions should be separated by semicolons (“;”).
For more information, see Internet Explorer uses Proxy Server for Local IP address even if the “Bypass Proxy Server for Local Addresses” option is turned on.
Use the Proxy setting in the Internet Explorer Customization Wizard
For more information about this method, see Use the Proxy Settings page in the IEAK 11 Wizard.
Use Group Policy
In earlier versions of the Windows operating system, Internet Explorer Maintenance (IEM) is used to configure Internet Explorer settings by using Group Policy. In Windows 8, the IEM settings have been deprecated in favor of Group Policy Preferences, Administrative Templates (), and the Internet Explorer Administration Kit 10 (IEAK 10).
To configure the proxy setting through a group policy, see How to configure Proxy Settings for Internet Explorer 10 and Internet Explorer 11 as IEM is not available.
More information
A proxy bypass entry may begin by using an,, ftp, or gopher protocol type.
If a protocol type is used, the exception entry applies only to requests for that protocol.
The protocol value is case insensitive. Multiple entries should be separated by semicolons.
If no protocol is specified, any request that uses the address will be bypassed.
If a protocol is specified, requests that use the address will be bypassed only if they are of the indicated protocol type. Address entries are case insensitive, the same as they are for the protocol type.
If a port number is given, the request is processed only if all previous requirements are met and the request uses the specified port number.
To bypass servers, use an asterisk (“*”) as a wildcard to replace actual characters in the exceptions area of the Proxy Settings dialog box.
Enter a wildcard at the beginning of an Internet address, IP address, or domain name that has a common ending. For example, use *. to bypass any entries that end in., such as and
Enter a wildcard in the middle of an Internet address, IP address, or domain name that has a common beginning and ending. For example, the entry * matches any entry that starts as www and ends as com.
Enter a wildcard at the end of an Internet address, IP address, or domain name that has a common beginning. For example, use to bypass any entries that begin as ,such as,, and
To bypass addresses that have similar patterns, use multiple wildcards. For example, use 123. 1*. 66. * to bypass addresses such as 123. 144. 12, 123. 133. 15, and 123. 187. 13.
Use wildcards carefully. For example, the entry * causes Internet Explorer to bypass the proxy for most websites.
If you bypass the proxy for a local domain, use * This method doesn’t use the proxy for any computer name that ends in You can use the wildcard for any part of the name. For more information, see The Intranet Zone.
Proxy Auto Configuration (PAC)
Example of a simple PAC file
The following is a simple PAC file:
function FindProxyForURL(url, host)
return “PROXY proxyserver:portnumber”;}
This PAC always returns the proxy proxyserver:portnumber. For more information about how to write a PAC file and the different functions of a PAC file, see Introduction of FindProxyForURL.
