## configuration details
* the server is not registerd with mumble → not on the public server list
* the bitrate is set to 128kb/s; otherwise the client would complainy that the server bitrate is less then the configured (default) in its local settings
* the mumble server needs special permissions on its SSL Files. The after acme hook ***should*** fix this, but it was never observed to be working (nor not working for that matter, but look here first, if there's any error with the certifcates)
