Coukd not establish connection woith local server process

Unity was working a few weeks back, then the next day, it suddenly wasn't working anymore. I was met with this error:

And when I tried to diagnose Unity, it gave me this report.

It seems I may have to fix my proxy server, but it turns out that I don't have one. How do I get a proxy server and configure it for Unity?

3 out of 6 checks passed:
[
{
"name": "UPM registry reachable",
"description": "Make an HTTP request to the UPM package registry",
"result": "FAIL",
"detail": "Connection error. This could be because a proxy is misconfigured."
},
