Mopidy with Iris/Spotmop - websocket issues


I got Mopid with Iris up and running - but there are still some issues that I can’t figure out. As far as I understand this seems to be related to interrupted websockets.

“Pusher” stays disconnected most of the time (sometimes it does connect but disconnects again). On the command line I get the following error message:

ERROR Uncaught exception in /iris/ws
Traceback (most recent call last):
_ File “/usr/local/lib/python2.7/dist-packages/tornado/”, line 412, in run_callback
_ callback(*args, **kwargs)_

Could somebody please give me a hint how to figure out this issue. At the moment I am pretty lost.

Thanks in advance.
