Bug FATAL: Unity requires internet connection to function properly

I just installed an asset and was wondering why the menus didn't appear. All I saw in the console was an unrelated error as listed below. I didn't associate the missing menus with that error. However after all tries failed I disabled some firewall settings. And all of a sudden everything worked as expected.

That's a FATAL error, that's absolutely unacceptable.

Here's the stack:

Windows. And yes, it's an office laptop with firewall / proxy setup. The application responsible is ZScaler:

https://www.zscaler.com/

Normally setup via admins. If I disable that application's Internet Security feature, everything works fine. I'm lucky to have admin rights and can do so, most don't have. So that's a critical issue imo.

Otherwise everything works, I can login to Unity, can download assets from the store, etc.
