Control Panel never redirects

Aight, so I tried these options, and they didn’t work. So I necro’d a few old posts and some people said using a vpn worked, so I tried using a vpn via opera gx and it finally worked. I want to thank everyone for there help and if anyone knows why did it just work with a vpn but nothing else? I tried everything that was mentioned changing internet allowing firewall using a public dns resolver. Nothing worked so why does a vpn work?
