Cant join to Servers after swapping Pc parts!

I recently swapped CPU + Motherboard and now I cant join any TeamSpeak server, same with Discord. It says “Verbindung zum Server Fehlgeschlagen”.
Have a great evening

Looks like your PC is blocking the connection?

Well, I can go to any website without problems, I write right now on my Computer.

Have you already looked at this topic? You can't connect to a server?

Nothing worked :/.

Well Acually Discord works fine on my phone. So it has something to do with my Pc?

Have you a Software installed like Anti Virus Software that could block the UDP Traffic?

Ensure that your firewall allows TS to connect. Also try running the application w/ administrative permissions.
