This sounds like the Wireguard client can't find a DNS server. Telegram and the other working apps either have the necessary IP addresses cached or built-in. Anything that needs DNS fails.
Does your DNS server accept request from the Wireguard network? Or do you have NAT correct on your Wireguard server?
Only workaround I've found is to warp to a different galaxy, summon the fighter there (and leave it there), and then portal back to whatever you're working on.

It's a huge pain.
The Angry GM has a recent article on exactly this!
Ummm... Weird question to ask?
