Hello! I've tried to create my own server eith my friend. I wanted to have a proxomity server, so I added the mod. I Downloaded and installed the mod to my minehut server but when i joined there was this cable with a red line across it. I pressed almost everysingle button on my keybeard, and when i came to "n" it said "voice not connected" and i've googled and i came up with that it meant something with the server port. I seached on youtube, google and i found a couple of ports examlple 25575, 25565 and a bedrock one 19132. I have no experience in these kind of things such as proxy, vpn, ip adress, port and i would really love to get some help.
