I installed mumble and murmur and I made an atuomatic certificate. I connected to a public server and my own server with the name Valeden using that certificate. I created my own certificate after learning a bit more about mumble and ended up replacing the auto generated certificate. I no longer can connect to the public server or my server under that name and I don't want to have to use another alias. If there is anything I can do to maybe get back the orginal certificate it would be nice to find out. I'd really like to go onto my own server with my actual alias.
Certificate is like a "password" key to your username,
if you can check in your server the user "Valeden" delete it and you can use your new certificate with that username, other is to use some other username on connect.
And if you like the certificate you have now, Export current certificate, store it to some backup usb stick or what ever you use, if you need to install computer from scratch for some reason, you have the certificate ready to import back.
