Help needed: Cast to HomePod not working

Hi, I have successfully added HomePod to Apple TV integration, however I can’t seem to cast to it, the aim is to use HomePod for TTS, which works on my phone, but when I try to cast to Homepod I got the error below:

Failed to perform the action media_player/play_media. HTTPConnectionPool(host=‘10.x.x.x’, port=8123): Max retries exceeded with url: /api/tts_proxy/4Uhglf65TSYpTGKqVYWCeA.mp3 (Caused by NewConnectionError(‘<urllib3.connection.HTTPConnection object at 0x7f25bbf5a580>: Failed to establish a new connection: [Errno 111] Connection refused’))

The HomePod is on a separate VLAN, however there is no firewall between and mdns is enabled. Does it use HTTP to cast? I also tried to play music to Homepod via HA without luck.

Any suggestion is appreciated!

I’m having the same issue, for what it’s worth. It was working and then stopped. Reboots fix nothing. Owntone has no trouble air playing without changes, but home assistant can’t do it.
