Unable to admin TS3 server

I have a TS3 server with Gameservers. I am no longer able to make any changes to it. I am trying to delete a channel and am no longer able to. I tried resetting privilege key at Gameservers and used the new key at “Use privilege key”. I keep getting this: Failed to use Privilege Key: duplicate entry". Any ideas. Thanks for any help.

You can do the following to solve this:

Generate a new privilege key

  1. Start any telnet client - you can use e.g. PuTTy
  2. Connect to your Teamspeak 3 server IP using Telnet on port 10011
  3. Login using command login serveradmin yOuR_nEwP@ssw0rd password in command is the same as the one you set for your serveradmin previously
  4. Select your Teamspeak server instance (if you have only one just this would be your default: use 1 and hit enter
  5. Now it’s time to generate new privilege key, for that use following command: tokenadd tokentype=0 tokenid1=6 tokenid2=0
  6. That will return you token, which you can copy and paste in Teamspeak 3 client under Permissions > Use Privilege Key
