If you are getting the error message “Wrong password for registered users, please try again” — this means that the user name you are trying to connect as has been registered on the server, and you don‘t have the matching certificate for that registered account.

This problem commonly happens when someone re-installs their operating system, and forgets to import the old certificate. There are three ways that this problem can be resolved:

Method 1: Import your old certificate

This is the best option if you still have a backup of your old certificate. To import your certificate click on ConfigureCertificate Wizard. Select the option Import a certificate and then follow the wizard to find your old certificate.

Tip: When you install Mumble, an automatic backup of your certificate is saved to your Documents folder, under the name MumbleAutomaticCertificateBackup.p12. If you haven‘t created a new certificate since installing Mumble this should be your current certificate backup.

Method 2: Use a different Name

Connecting under a different user name (one that is not already registered on the server) will allow you to get back into the server right away. You will need to do this for every server that you were registered on.

Method 3: Delete the old registration

Ask one of the users on your server who have administrative access to delete your old registration. They can do this by clicking on ServerRegistered Users, and then highlighting your name and clicking the Remove button. If you have the SuperUser password to the Mumble server you can log in as SuperUser and perform these steps yourself.

As with method two, you‘ll need to do this on every server you registered with.
