Why is my VPN connecting only to WireGuard (TCP)?

Hello, I've decided to try a VPN because i'm unable to play a lot of multiplayer games because for some reason I cannot join/connect to most servers.

For example, in valorant, only one of the servers work, and.....well...it works only 1/4 of the time.

Cannot play fortnite, rust, gmod, stuff like that at all.

And so, I've activated the one month cheap promotion plan, but.....now, my VPN connects ONLY to WireGuard TCP, and games "misbehave" because of it [still, it DOES at least let me connect to other servers, it seems].

For example, in valorant, the "social" functions do NOT work, for example it says "chat is unavailable", etc.

It also seems like I can only connect to ONE specific vpn server in my country.

Any ideas what's wrong?
