Music plays only once

I use mopidy with Iris and I can play one song but no matter what I do it can’t run another one after the first one. I always have to restart the service. I looked through the logs and found this error occuring:

Do you know what’s going on ?

Does this only happen when listening to YouTube? Looks like Mopidy tries to access a webm images, and then gets redirected to an empty URL. If you’re using the YouTube extension then that might be where the issue is.
