What to Do If Your Proxy Server Is Refusing Connections An error has occurred in Firefox

It says “What to Do If Your Proxy Server is Refusing Connections An error has happened in Firefox” and we can see what to do.

Please read this page if you are using the Mozilla Firefox or Google Chrome browsers on a Windows computer and receive an error message saying “The proxy server is blocking connections” when attempting to see an Internet-facing website. Despite the fact that we’ve taught you how to troubleshoot Firefox, you’ll need to do the same thing with Chrome, as well.

This problem commonly occurs when you are using a virtual private network (VPN) service or when you have an inaccurate or expired proxy setup. This problem can also arise if your computer has been infected with malware, which has the effect of modifying internal settings.

Method 1: Make Firefox detect proxy settings automatically

Open your Mozilla Firefox browser and navigate to the action button, which is located in the top-right corner of the screen. Choose Options from the newly appeared context menu that appears.
Once within the Options tab, select the General category from the vertical menu on the left side of the screen, and then use the right-hand side menu to scroll down to the Network Settings section. To access the advanced menu when you arrive, pick Settings when you first go to the site.
Following your successful display of the Connection Settings menu, change the toggle associated with Configure Access to the Internet from ‘Use system proxy settings’ to ‘Use system proxy settings’.
Upon completion of this modification, click OK to save it, then restart your browser and attempt to visit the same web page that was previously failing.
If the problem message “The Proxy server is rejecting connections” continues to appear, continue to the next possible remedy listed below.

Method 2: Adding the SSL port of the URL to the list of authorized ports (if applicable)

Investigate the URL that is triggering the ‘The Proxy server is refusing connections’ error to see whether it has any evidence of a currently functioning port.
Once you’ve located the issue port, navigate to your proxy configuration settings and check for an option to include the port as an additional SSL port.
After that, you should save the configuration and restart your computer.
Check to see if the problem has been resolved when the next computer setup has been completed.
If the problem remains after attempting the steps outlined below, or if this strategy is not applicable, proceed to the next available option.

Method 3: Switching to an HTTPS Proxy is the third option (if applicable)

The error message “The Proxy server is rejecting connections” may appear while attempting to access an FTP site through an HTTP proxy. HTTP proxy servers, in contrast to HTTPS proxy servers, do not support this feature.

If this scenario applies to you, you can resolve the issue by using an HTTPS proxy solution, which ensures secure communications from the beginning to the end of the transaction. To find suitable SSL Proxy servers without having to pay for a premium service, you can use this website to search for compatible servers.

Whether or whether you are experiencing difficulties accessing a website using FTP, continue reading to the next probable remedy below.

Virus and adware scans should be performed on your machine.
