web server receioved an invalid response
When trying to access Norton support by selecting help and then support I get the following error: 520 - Web server received an invalid response while acting as a gateway or proxy server. I can access the page with Edge. This is on a new lap top with Norton and Fire Fox installed. Everything else in Norton seems to be working fine. My desktop also has Norton and Fire Fox and I have no problem accessing the page with fire fox on the desk top. Help!!

Thank you. I was able to get on Norton support using Edge, but I am trying determine why I am having the problem with Fire Fox. I do not have the problem on my desk top machine while using Fire Fox
