Get your webhosting fixed.

It's not a hosting side. When I stop using squid all access is well. I focused on squid issue?

Thank you.

Just because you are getting a message from Squid when using Squid doesn't mean it's a Squid problem. Squid got a connection reset from the server (or from something else in the way). That's all. Go figure why the server is resetting the connections. Perhaps they use some "helpful" IDS/IPS in place doing this when someone accesses WP admin via a proxy (yes, I have seen those).

Squid isn't doing anything here. It simply received RST before it expected that to happen.
