Edge Beta not working on network. Worried about upgrade!

[gsbws]

A few computers at my organization use Edge Beta. About two months ago every Edge Beta installation stopped working: "Page not found "the connection was reset""

I'm not seeing any logs in our Sonicwall of anything being blocked. Does anyone have any idea what be causing this. I want to push the upgrade but I don't want to break everything!

I should add that disabling Windows Defender Firewall doesn't make a difference.

Correct me if I'm wrong but "the connection was reset" != a crash

Anyways, I tried everything you posted and it doesn't help the problem.
