Investigate a Plasmo Voice not-installed message before changing ports

Applies to: Plasmo Voice; match the linked maintainer documentation to your installed platform and release.
Documentation checked .

The client’s not-installed message indicates failed detection between client and server. Plasmo Voice documents this separately from UDP reachability, so start with versions and plugin channels instead of changing a working allocation.

Prepare the test

Record client and server major versions before comparing results. Keep the Minecraft connection, voice handshake and UDP audio path separate when deciding which setting or log to inspect next.

Make the change

  1. Record the exact client mod version, server plugin version and Minecraft implementation. Compare their major versions first: the project documents that the 1.x and 2.x voice protocols cannot detect each other correctly.
  2. Confirm the server actually loaded the intended build by inspecting startup. On the client, verify the mod is present in the launched profile rather than merely downloaded into another instance or launcher directory.
  3. Test with a minimal compatible client profile if your pack includes a mod that hides its mod or plugin-channel list. Keep the original profile intact and change only that variable before reconnecting to the same server.
  4. If detection still fails, capture matching client and server logs around one fresh join. Enable the documented debug mode only for that short reproduction, then turn it off and redact personal data before sharing the evidence.

Check the result

The client should recognise that Plasmo Voice is installed before you proceed to an audio-path test. Then check nearby two-way speech; successful detection alone does not prove the separate UDP endpoint carries audio.

If the test fails

Return to the original client profile if the minimal profile changes nothing. Provide the exact versions and handshake evidence to support instead of opening extra ports, replacing the world or deleting the voice configuration.

Consult the current troubleshooting page for release-specific handshake fixes. Avoid promising that an old version’s workaround applies unchanged to every later client and server combination.
