"Pairing Not Possible" with HomePod in Home Assistant

Describe the bug

When attempting to setup any HomePod in Home Assistant, the following error appears:

Ultimately, hitting “Submit” repeats the failure message with the other protocols, before receiving a final “Aborted” dialog.

This is with the latest hass-atv-beta installed via HACS. Running Home Assistant 2021.10.0 (though it also had the same issues with earlier versions). This is in a Docker container running on my Synology NAS, though it is using the host networking.

Worth noting that setting up an Apple TV seems to work fine. I’m also not getting any of my devices automatically popping up as “Discovered,” which also seems to be some kind of issue.

Home Assistant logs are attached, please let me know if there are other logs I should be looking for.

Great! I guess we can close this now!

I seemed to have resolved this one: While digging around other issues here, I saw reference of deleting old Apple TV instances in the .storage/core.config_entries file. I did that, rebooted and voila - the remaining HomePod/Apple TV instances appeared in discovery. Thanks for the help on this!

Edit: This also resolved the above error from appearing in my logs thousands of times.
