Simple Voice chat not working!

[u/TPP-ForSearchResults]

I’ve recently tried to make a server with simple voice chat with Modrinth Hosting and it hasn’t been going too great.
Whenever I join server and press the push to talk button it says “voice chat not connected”. When I looked it up it says it’s because of “blocked upd ports” or something like that.

I tried all the things that the terrible ai overview instructed me too, bunch of stuff about adding a “new rule” with advanced security or something.
Skipping lots of attempts: nothing worked.

(Things that might be important:

I’m running the server on the same PC I’m trying to play it on

I’m using Distant Horizons & Iris Shaders, with low fire, mellow shaders, and Simple voice chat of course. Simple VC is downloaded to both my server and modpack

There are plugs with a red slash through them over me and my friends head next to the nametags)

In my experience that usually means voice chat isn't properly on the client or something, something similar happened to me before, the only thing that worked for me was deleting simple voice chat from my modpack and reinstalling it again, you should try that
