TS6 Client (beta5) fails to connect to TS6 Server (beta12.1) with error "parameter not found" – TS3 connects fine

Hello everyone,

I’m having a persistent connection issue with the TeamSpeak 6 client and would like to know if anyone else is experiencing the same problem or has a solution.

Problem:

  • I cannot connect to a self-hosted TS6 server using the TS6 client.
  • Error shown: “parameter not found”
  • The same server works perfectly with the TeamSpeak 3 client.

Details:

  • Client version: TeamSpeak 6.0.0-beta5 (Windows 11)
  • Server version: 6.0.0-beta12.1 (Linux)
  • Server is using a custom voice port (not the default 9987)

What I already tried:

  • Clean reinstall of TS6 (deleted all folders in AppData, LocalAppData, etc.)

  • Deleted cache

  • Created new identity

  • Tried with VPN

  • Tested using mobile hotspot

  • Confirmed that other servers (including official ones) work fine with TS
    Relevant log lines:
    [info] Connecting to [server]:[port]
    [info] server sent ciphers:1
    [info] Selected cipher:0
    [warning] Error while parsing packet: parameter not found
    [warning] Got command data while disconnected, dropping
    [error] setWhisperReceiveMode: Didn’t find connection for id X
    It seems the client successfully reaches the server and exchanges ciphers, but then fails to parse a packet coming from the server.

    Is this a known compatibility issue between client beta5 and server beta12.1?

    Has anyone else run into this error?

    Any help or information would be greatly appreciated.

    Thank you!

Hey, i added you in TS6, it would be nice if you would accept me so we can try to figure out what happens there

I’m having the same problem how can I resolve it?

Sent me a private message with the affected server and we can see what the problem is.
