Every morning error

I have a remote mopidy server on a Raspi-3b that is always playing except in the night. It is stopped in the evening (Iris clear queue) for the whole night. When in the morning I start playing a radio stream, I always get this error message in the log:

Jan 6 09:00:28 pab mopidy[485]: ERROR GStreamer error: gst-resource-error-quark: Server does not support seeking. (11)

All I can do is to restart the service.
