UDP packets problem Windows Dedi Server

Hi.
I’m using a dedicated windows server 2022.
I have open ports and everything is normal until anyone tries to connect to the server.
The server is loading on my server list but, after clicking connect loading resources, I get this error:

Port 30120, and 30110 is open, and resources are loaded but still can’t connect.
Does anyone know how to solve it?

Thanks!

I dont suppose you managed to fix this?
