Check the message “The proxy server is refusing connections”

Can it be said that you cannot connect to the Internet because you are getting the error message “Intermediate server is refusing connections” in Mozilla Firefox? Assuming this is the case, sit back and relax. There is an exceptionally basic solution to this problem. This is an issue with incorrect proxy server settings in Firefox.

Fix “Proxy server refuses connection error” message

Force Firefox to automatically detect proxy settings

It turns out that this particular issue can also occur due to the way Firefox is configured to deal with proxy servers by default. Unlike many other proxy servers, Firefox will not adopt the system-wide proxy services that are used for the network you are currently connected to. Luckily, you can change the default settings to force the browser to automatically detect proxy settings for this network, which will eventually fix the problem.

Several affected users have confirmed that this operation finally allowed affected users to visit all websites without encountering the “Proxy server is refusing connections” error. Here is a quick guide on how to access Mozilla Firefox’s network settings and change the default connection settings so that the HTTP proxy and network-wide port are adopted.

  • Open your Mozilla Firefox browser and click on the action button at the top right of the screen. In the context menu that has just appeared, click on Options.
  • Once in the Options tab, select the General category from the left vertical menu, then use the right menu to scroll down to Network Settings. When you are there, click on Settings to bring up the advanced menu.
  • Once you’ve successfully brought up the Connection Settings menu, simply toggle the toggle associated with Configure Internet Access to “Use system proxy settings”.
  • As soon as you make this change, click OK to save the changes, then restart your browser and try to access the same webpage that was failing earlier.

If the same “Proxy server is refusing connections” error still occurs, please move on to the next potential solution below.

Add SSL port URL to allowed list (if applicable)

Another scenario that causes this issue is a situation where the end user attempts to access a URL that contains an alternate port for an SSL connection. Some proxy solutions, including EdgeWave iPrism, will treat this as a potential security hole. If this scenario applies, you can fix the problem by going to your proxy server settings and adding the port as an alternate SSL port.

Of course, the steps to do this will be very different depending on the Proxy solution you are using. But to make it easier for you, here is a general guide you can use to add the blocked SSL port to the allowed list.

  • Examine the URL that triggers the “Proxy server is refusing connections” error to see if it contains evidence of an actively used port.
  • Once you’ve successfully identified the problematic port, open your proxy settings and look for a setting that allows you to add the port as an alternate SSL port.
  • Once you’ve done that, save your settings and restart your computer.
  • After the next boot is complete, check if the problem is resolved the next time you start the computer.

If this problem is still not solved after following the instructions below or if this method is not applicable, please proceed to the next potential solution.

Switch to an HTTPS proxy (if applicable)

You may also encounter the error “The proxy server is refusing connections” when trying to access an FTP site through an HTTP proxy. Unlike HTTPS proxy servers, HTTP proxy servers do not allow this. If this scenario applies, you can solve the problem by switching to an HTTPS proxy solution that guarantees end-to-end secure communications. If you don’t want to pay for a premium service, you can use this site to find viable SSL proxy servers you can use. If you cannot find the issue when trying to access a site with FTP functionality, please proceed to the next possible solution below.

Disable the built-in proxy server (if present)

Another scenario that will eventually cause this problem is if a proxy server is enabled in your local area network (LAN) settings without your knowledge. Even if you purposely use a dedicated proxy solution, you should use a trick in the Internet Properties tab and see if you are not actually using two proxies at the same time. This regularly happens after a computer has been attacked by malware or adware. Some viruses will deliberately adjust your proxy settings to redirect you to spammy ads. Many affected users reported that they managed to fix the issue completely after disabling the built-in proxy feature in the Internet Properties tab.

  • Open a Run dialog box and press Windows key + R. Next, type “ms-settings:network-proxy” and press Enter to open the Proxy tab of the Settings menu.
  • Once you’re in the Proxy tab, use the menu on the right side to scroll down to the Manual proxy settings section and turn off the toggle associated with Use a proxy server.
  • Once this tweak is applied, restart your computer and see if the issue is resolved the next time you start the computer.

  • Once you manage to enter the local area network (LAN) settings menu, navigate to the proxy server settings and uncheck the box associated with “Use a proxy server for your LAN”
  • Once the proxy server is disabled, restart your computer and see if the problem is resolved the next time you start the computer.

Uninstall the VPN client (if applicable)

It turns out that Firefox doesn’t have a specific error message indicating a problem caused by a VPN network. So, if you’re using a VPN client that really makes it easier for this problem to occur, you can expect to get the same error message (proxy server is refusing connections).

If this scenario applies, you can fix the problem simply by disabling the VPN client causing the problem. If that’s not an option, the only option left is to uninstall the VPN solution entirely. If you’re out of options, here’s a quick guide on how to uninstall the VPN client from your computer.

  • Press Windows key + R to open a Run dialog box. In the text box, type “appwiz.cpl” and press Enter to open the Programs and Features screen. When prompted by UAC (User Account Control), click Yes to grant administrative privileges.
  • On the Programs and Features screen, scroll down the list of installed apps and locate the VPN client you are actively using. Once you manage to find the VPN solution, right-click on it and choose Uninstall from the pop-up menu that just appeared.
  • Follow the on-screen prompts to complete the uninstallation, then restart your computer and see if the problem is resolved the next time the system boots.
