I am trying to install the mod and it keeps saying voice chat not available. I have changed the port in the server config and I changed it to the minecraft port since the port is open in my network and it still didn't work. Then I used Netcat to try to fix it and it still isn't working. So what am I doing wrong?

Did netcat work?

I want to make a server with voice chat, have u make it work? I need help xd
