Plex on new subdomain not recognized by local network chromecast for Google TV

Plex Players

Server Version#: 1.26.0.5715
Player Version#:

I’m using my variation on docker-compose setup: https://github.com/rosskevin/mediabox

I’ve got all services running, downloading, and usable with oauth and subdomains via any web browser.

I’m switching from a local, unprotected, no subdomain plex server.

My typical viewing device is Chromecast for Google TV. When I open Plex > More I see my plex.example.com with a warning icon.

I can view anything with the web browser, but that requires an oauth (GCP sign in). How do I get chromecast to be allowed on the server? Or at least, how do I see logs as to why Chromecast is NOT seeing the plex server.

I have remote access disable. I assumed I would not need it since everything is local?

If this is local to server you can try setting Allow Insecure connections to, on the local network, or always.

if you are using the app not casting) then it is the Android TV app. this is is a link on how to get android logs

Thank you

My key mistake was not disabling cloudflare caching with a Page rule. So at least that allows the client connection and streaming.

Now, while my traffic shows as local, all the playback qualities are at the lowest setting (and 4k with hardware acceleration is unplayable) - so I’ll have to look in that next. I may look at pulling logs if I can’t find any other reason the stream is downrated.

Did you resolve this issue? Or was it just defaulting to low settings and you could set it to original playback?

Yes, regarding the qualities.

Details are here: GitHub - rosskevin/mediabox: 🐳 docker-compose based MEDIABOX 📺

Ultimately, I was trying to run the Plex container on a docker-compose network and open up all the ports. I just could not get it to work, and it is not the recommended way. Instead, I switched the plex container to the recommended network_mode: host networking, while others were using the docker compose network, and immediately it solved the problem. Default to highest quality on playback. mediabox/multimedia.yml at master · rosskevin/mediabox · GitHub

thats a routing error. Plex is advertising the docker subnet IP when in bridge mode. You’ll have to tell the router on the host subnet to route the docker subnet to your host.
