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.
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.

FIX: The Proxy Server Isn’t Responding – Appuals.com
“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!

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
