pychromecast.socket_client heartbeat timeout, resetting connection and other errors

The problem

All google home devices on the home network are systematically registering logging entry WARNING messages about timing out on the heartbeat. We have about 10 devices on the network and every one of them is doing it. We have google home mini’s, max, home hub, original google home.

Another interesting thing happens when i try to turn on one of the google home devices in home assistant. When i push the power button on say a google home mini, i get this message:

2021-08-12 11:03:04 ERROR (Thread-12) [homeassistant.components.cast.media_player] Failed to cast media https://www.home-assistant.io/images/cast/splash.png. Please make sure the URL is: Reachable from the cast device and either a publicly resolvable hostname or an IP address

Which is weird because its trying to cast a PNG image to a google home mini device. Almost seems like its identifying the devices as the wrong model. I tried turning on another google home mini, same error message.

I tried to research my error here before coming to post here. Apologies if this was previously covered. Just installed a fresh install of HASS OS on an rpi4. . Have been testing the Google Cast integration & all tested media plays perfecly (mp3 audio files, casting using the Spotify integration, and YouTube). Speaker group playing works & end point media controls work as well. Have tested with a Nest Hub, a few Google minis, Chromecast, Android TV and TCL Smart TV. Even got the tts speech to work quite well. All changes to volume, channel, media, on the cast receiving device instantly reflect back in the entity properties. But when idle, this timeout error has been piling up.

Thanks much to all in advance

I’m on 2022.4.3 and am experiencing the same warning and errors as above. Is anyone still experiencing this? I have probably a dozen Google Nest smart speakers, displays, chromecasts, and chromecast audios all giving the same warning and errors. Going to attempt to delete and setup the integration again to see if that resolves it.
