Unity NOPROXY

Hello everyone,
I've installed Unity Hub, and then Unity 2019 and 2020.
On both versions, when I try to open a project, it pauses on "Starting server" and then throws me an error saying that Unity Package Manager could be blocked by a firewall or anti-virus.



When I set the environment variables HTTP_PROXY, HTTPS_PROXY and UNITY_NOPROXY, to the value "localhost,127.0.0.1", it works. But inside Unity, I'm offline. And so, I can't download packages or use Asset Store.

If I don't use these values on the environment variables, I can't open Unity.

I'm not using any antivirus and I don't have any proxy at all.

The diagnose tools says no error at all.
