The server crashes with the voice chat mod

Minecraft servers 3 views Updated 2 Aug 2026

What to do if the voice chat mod takes the server down on startup.

The voice chat mod needs a UDP port and a specific configuration. If it's wrong, it can take the server down on startup.

Fixes

  • Check the mod config: in config/ (Fabric/Forge) or plugins/ (Paper), set the voice port to the one assigned to your server.
  • If you just want to get out of the crash quickly, remove the voice mod/plugin (take it out of mods/ or plugins/) and restart. The server will boot again.
  • Re-add it with the correct port once you're sure.

Not sure which voice port to use? Open a ticket and we'll tell you the right port for your server.
