Snapsever: "Error in socket shutdown: Transport endpoint is not connected"

[Sungod3000]

Hi,

I have mopidy, snapserver an snapclient configured and running. I can play music on mopidy locally, but when i try to connect to snapcast I cant play anything.

The snapclient status is clean, no errors.

However in the snapclient status message I get

pi@raspberrypi:~ $ sudo systemctl status snapserver

Can someone explain where this transport endpoint is supposed to connect to? and what is this control socket?
Is this maybe just a configuration issue like some IP somewhere not set correctly?

Cheers
