Google Cast stops working after a while

Google cast will work immediately after restart but then after time, I will get errors like the following:

Error executing service <ServiceCall media_player.play_media: media_content_id=https://myurl/api/tts_proxy/deaf407043854a7a2fd19b7f8584c77394d44940_en_-_google.mp3, media_content_type=music, entity_id=[‘media_player.audiogroup’]>

I have just started getting the same problem as well with 0.64.3 Never had a problem until now. Rebooting fixes the issue for a while as you say.

Same issue here. Anyone discover a fix yet besides frequent reboots?

Seems to be fixed after update

I nave the same problem from One month.
After the last update of ha core cast doesn’t work and if i play a Song doesn’t work.
No message from log.
The entity in cast integration are online.
Reinstalling the integration doesn’t fix the problem.
