Sonos media player stuck in paused state

I have a Sonos Play speaker that’s been working great with automations until a few days ago, now it’s stuck in paused state. I can manually change the state to idle in dev tools, but running the automation which plays a local media file. As soon as I attempt to play the file, it jumps back to the paused state. Other Sonos media players do the same thing - both when playing the file manually from the player and from an automation.

UPDATE: Playback works fine when playing from a network media source. IT seems to be failing only with local media.

Solve with an idea from this related post. Turns out my local HA URL was incorrectly set. Changing that to the proper URL made everything work again.

Can you give an example of what you were using before and now? I’m currently using

http://ip:port/media/local/file.mp3

And it seems to randomly go idle and pause
