Configure voice chat plugins correctly

Simple Voice Chat and Plasmo Voice on PenguHost: the port, the config lines and the two settings that cause "voice chat unavailable".

Proximity voice chat works on our servers; it just needs its own UDP port.

Simple Voice Chat (Paper/Fabric/Forge/NeoForge)

  1. Add a port. Note its number.
  2. Install the plugin/mod via the *Plugins*/*Mods* tab. Restart once to generate the config.
  3. Edit plugins/voicechat/voicechat-server.properties (mods: config/voicechat/voicechat-server.properties):
port=<your extra port>
bind_address=0.0.0.0
voice_host=node1.penguhost.com:<your extra port>
  1. Restart. Players install the same version of the mod on their client; the in-game overlay shows a green icon when connected.

Plasmo Voice

Same idea: plugins/PlasmoVoice/config.toml → port = <extra port>, ip = "0.0.0.0", and set host.ip/host.port to node1.penguhost.com and the port.

"Voice chat unavailable"

  • The port in the config is not one of your allocations → check the Network tab.
  • voice_host empty and the game port differs from the voice port → set voice_host explicitly.
  • Player's client mod version ≠ server version → update both.
  • A firewall on the player's side blocking UDP → rare, but test with a phone hotspot.
