frigate: Frigate clips do not play on remote devices in Home Assistant

Describe the problem you are having

I started exploring implementation of https://github.com/dermotduffy/frigate-hass-card/issues/439 , and realized that I cannot get HA to play any Frigate clips on remote media players.

Steps to reproduce:

• Open the HA media player (sidebar -> ‘Media’)
• Choose ‘Frigate’
• Choose ‘Clips’
• In the bottom right use the device selector to choose any device other than ‘Browser’
• Click play on any clip.

Expected behavior:

• HA should play the media on the remote device.

Observed behavior:

• The chromecast logo will appear on the target device, but the media will not play. The HA logs contain:

2022-05-01 16:23:44 ERROR (Thread-14) [homeassistant.components.cast.media_player] Failed to cast media https://[HA]/api/hls/0c7cf72cdcf07935f13b933daa682bc501338a1340553c29ff35ec389849766/master_
playlist.m3u8?authSig=[AUTH] from internal_url ([HA]). Please make sure the UR
L is: Reachable from the cast device and either a publicly resolvable hostname or an IP address

Initially I thought this was either an error on my end, or a problem with the integration. However:

• Other media (e.g. random HA cameras) work just fine casting to the same devices from HA via the same steps above. It is Frigate event media only that will not play.
• In chatting with @NickM-27 on discord, he observes the same – but found some clips for some cameras that do work, which make it less likely this is an integration issue vs a Frigate or video issue.
