trouble connecting to proxy

[mackevicius]

hello im trying to connect to a proxy but i keep getting this error message: your computer appears to be correctly configured but the device or resource (web proxy) is not responding


Please help how do i fix this?

EDIT: I already scanned my pc for any viruses with malwarebytes multiple times even in safe mode and nothing came up so this is not the problem.

I also turned off my firewall and still doesnt work

What way are you connecting to a proxy? Have you tried resetting your PC's network settings and reconfiguring again? Router firewall settings?
