I can't get mopidy-soundcloud to play anything

I’m able to install mopidy-soundcloud without errors and mopidy runs without errors. I’m able to search for songs on soundcloud but when I try to play them I get this:

Hey, it looks like you and I ran into the same issue at the same time. It’s posted at Soundcloud no longer works, tracks aren’t playable.

As of a few hours ago the SoundCloud links mysteriously started working for me again.

Can you confirm that they also work again for you now?

Yes, it appears to be working now… sigh…

I bumped into the same problem that soundcloud playback seems to first work just fine, then stops working and later works again.

Looked a bit into this and seems that in my case the reason is rate limiting performed by soundcloud at their backend. When playback does not work, try to fetch https://api.soundcloud.com/tracks/[trackid]/stream and you will see an error like below indicating that rate limiting has kicked in:

$ curl https://api.soundcloud.com/tracks/200749801/stream?client_id=93e33e327fd8a9b77becd179652272e2
{“errors”:[{“meta”:{“rate_limit”:{“bucket”:“by-client”,“max_nr_of_requests”:15000,“time_window”:“PT24H”,“name”:“plays”},“remaining_requests”:0,“reset_time”:“2018/05/04 13:02:05 +0000”}}]}
