Create a server on 1.18.2, in TLauncher. I configured all the mods, and when I went to the voicechat config, and put the port that appears in my server console, when I enter my world it says that the voice chat is not connected. I do not know what else to do..
For all those who doesn't have the config folder, it's because you have a forge server. You can find the folder in world/serverconfig and there is the config file for every single mod that you have installed in your server. :D Hope it works!..
