My Question or Issue

Dear Spotify,

I have been using "Transfer Playback" api but it doesn't work sometimes.

In the official api pages, same as in my own application, the api returns 502 Bad Gateway error and doesn't provide any other information.

How can I fix this?

Please give me some help to resolve it, or please fix this if the problem occurred in the Spotify's API side.
