That's a strange bug, might be related to an application specific firewall, VPN or similar, though, I'm not sure I can actually look into this without being able to reproduce it in any way... Mostly because this isn't entirely in Viper's control, best Viper can do in this situation is show a better error message :/

I will keep this open in case it's an actual issue and not just a network misconfiguration of some kind.

Yeah pretty sure Viper is blocked from internet access in this case

So way to go would be to have a connection check (ping cloudflare, google, ) and show user friendly error message accordingly.

Definitely something blocking network connection for some applications

We actually do have a check for navigator.onLine albeit, it isn't always accurate, I do however realize now, it is only ever checked on startup. I'll look into making it check more frequently, and doing extra checks to remedy/help with this...
