When I try to download something...anything!...of late, I get the above message. Cannot connect to proxy server. I don't even know what a proxy server is, for Pete's sake!
Are you using Internet Explorer? If so go here: From IE > Tools > Internet Options > Connections tab > Lan settings button.
Uncheck the box which says "Use a proxy server for your LAN".Let us know how you get on. It raises a question about why it became set (if it is) so we will then need to then run a couple of free programs at least, just to see if you have some virus or malware about.
Always pop back and let us know the outcome - thanks
