@tagomago Oh OK, I forced it pausing the stream for a long time and yes, the alert you describe appeared and the stream got disconnected.
I guess it’s just a buffer overflow, so then the app tries to get to some point in the stream that the server won’t serve, and the error is raised. The buffer size (Settings > Backend > Buffer > Buffer duration) is limited to 9999 ms, so that won’t solve it (probably it’s not even related to streams?).
I guess there’s room for improvement in the way the app handles this. Trying to reconnect could be nice, probably?
