Hello and Good Afternoon Everyone,
I wish to help my supervisor who is also a good friend with what appears to be a browser issue. Whenever he attempts to get onto the internet using Internet Explorer 11, he gets the following error message: The proxy server isn't responding. The suggestions he gets to correct the problem is as follows: 1. Check proxy settings 127.0.0.1:13081 , 2. Make sure firewall isn't blocking web., 3. Check LAN settings, and 4. Ask a system administrator for help. Interestingly, all other computers with the wireless connections are working just fine. He also remembers receiving a message indicating the computer is correctly configured but the DNS server is not responding.
The problem is with the main computer with the hard wired or ethernet connection to the Comcast receiver.
With respect to a possible cause, he said he only noticed the problem after using Malwarebytes. Personally, I can not see how this program could have caused the issue because I have used Malwarebytes several times in the past and without problems. Just from the sound of things, I believe there is an invalid browser setting. Of course, I am speculating and could be wrong here.
Just in case it is needed, the operating system is Windows 7 in case any changes need to be made within the operating system as opposed to the browser.
In closing, thanks so much in advance for any attention and suggestions given to this question. I will look forward to reviewing all feedback given.
