Cannot Chromecast even with TLS certificate

Plex Media Server
1

Server Version#: 1.25.2.5319
Player Version#: 4.66.1

Plex Media Server is correctly configured with a valid Let’s Encrypt certificate. DNS points to the correct location. Loading Plex via its FQDN works like it should. The Chromecast icon is completely disabled; this is an intentional limitation of functionality by Plex developers.

I should be able to cast to devices from my own server, even if it is not signed in to plex.tv. This is vendor lock-in at its finest. Please change this behavior so that I can cast video to LAN devices even if I don’t have a Plex account.

Did you add your certificate to Plex,
Tell Plex to ignore the LAN IP of the chromecast,

or did you ignore all that when you made your determination that it’s deliberate?

Do you have the debug logs to zip file to support your claim? It might actually be a bug

90+ % of what is seen with certificates is due to not understanding how Plex manages and interacts with properly signed FQDN certs.

  1. Did you add your certificate to Plex?
    • Yes, else I couldn’t have stated that “loading Plex via its FQDN works like it should.”
  2. Did you tell Plex to ignore the LAN IP of the Chromecast?
    • Yes, my whole LAN subnet is whitelisted.
  3. Can I cast to the Chromecast from Chrome itself and from all my other devices on my LAN?
    • Yes.
  4. If the server is unclaimed/not signed-in, is the Cast button enabled and simply pops up with “you cannot Cast without a secure connection to plex.tv”?
    • Yes.
  5. Even if the server is claimed but Plex is loaded via IP address, is the Cast button enabled and simply pops up with a “you cannot Cast without a secure connection to plex.tv”?
    • Yes.
  6. Even if the server is claimed and Plex is loaded over TLS via its FQDN, is the Cast button then disabled (the only time it is disabled)?
    • Yes.

May I see the DEBUG log files of this happening?

Also, one final question about the cert/fqdn. I presume it’s a Let’s Encrypt or other agency certified and your P12 does include the CA for Plex to authenicate with?
