Maybe do a trace with wireshark and compare the connection attempts?
Most website blocks are done on a dns level, maybe vivaldi doesn't accept the "wrong" dns replies, uses DNS-over-HTTPS or doesn't query any affected dns servers.

I have secure DNS set up on all my devices, this isn't a DNS level block. I tried looking at the chrome Dev tools connection page and I would try wireshark too but idk what to look for, especially when I'm trying to figure out why it works
Edit: I'm pretty sure with normal DNS you get a page saying it's blocked for discord
have you tried setting your dns to the opendns servers, if yes, what were the results?
No change, vivaldi still connects other browsers still don't
Probably just uses a fallback DNS service when the "official one" fails
I'd recommend to not use ISP DNS in general.
