TS3MusicBot is Discord compatible!
To solve this:

1. Open your TS3MusicBot webinterface.
2. Login with the admin password.
3. navigate to the following url:
Code: Select allhttp://botip:botport/remove6

Example: If your webinterface address is:
Code: Select allhttp://

then you open:
Code: Select allhttp://

This will remove the identity and creates a new one for the new client.
