Spotify Web Playback SDK: 404 device not found

[john_insomniac]

We are getting 404 message when trying to play music on our embedded Spotify player. 

We did not change anything in the code, the app just stopped working. 

This is now a big problem that has appeared on multiple threads in the forum and I don't understand why Spotify doesn't fix it. 

We CANNOT make an app with Web Playback functionality at all - all playlist sites and other sites with an embedded player will not work, the same as ours is not working. 

Spotify, can you look and fix this issue??

I guess your app tries to play on a device that's offline or doesn't exist anymore.
If you get this error, look if you can see your app in the available devices list with the get-users-available-devices endpoint.

Yes, we can see the device. But as soon as it is registered, it goes offline.
