Mumble server not booting

my internet went down today and that changed my IP and such. After that my mumble server has been acting strange.

When trying to boot the server my log says:

    <W>2015-03-25 19:30:03.769 Initializing settings from /etc/mumble-server.ini (basepath /etc)

The server is running on a RaspberryPi with Raspbian.

I saw someone saying its trying to use IPv6 but saw no fix. I tried adding a couple of lines to sysctl to disable IPv6 but that didn't work either. I've obviously rebooted everything etc. I've tried changing the port but that didn't change anything.

Before i unplugged the Raspberry my log gave me:

    <W>2015-03-25 19:38:57.733 1 => Server listening on 0.0.0.0:64738
    <W>2015-03-25 19:38:57.771 1 => Failed to set IPV6_RECVPKTINFO for 0.0.0.0:64738

But those disappeared.

So now I'm stuck and have no idea how to go about fixing it.

Any help appreciated!
