Server Version#: 4.158.0
[Req#cdd/Transcode/Req#ce0/MetadataAgentManager/getAgent] Unable to find metadata agent provider for identifier ‘https’
This is my “PC Load Letter? The ■■■■ does that mean?” It seems really weird that Plex would barf on HTTPS trailers in 2026.
You might need provide a specific example so other folks can check to see if this is an environmental/regional issue.
If you have pre-roll trailers enabled and try playing a movie, any movie, almost all trailers fail with this error.

Could you be more specific as to what information you’re looking for?
Is the issue occuring when using a Plex client within the same local network as the server? If so, it is likely caused by an issue with DNS. The app expects a secure connection to the server in order to load the preroll.
However, secure connection means your server has to be available under its own sub-sub-domain on the plex.direct domain in the local network. Which in turn requires your local DNS resolver (usually in your router) to be able to deliver that.
Since the DNS master server for all *.plex.direct domains is located outside of your local network, many local DNS resolvers refuse to use it for a host within the local network.
This is called “DNS rebinding protection” and is usually a good thing – except in this particular case.
If you can, define an exception from the protection for the domain plex.direct. And/or use a different DNS server than the default one assigned by your ISP.

(side note: if you have set “Secure Connections” to “preferred”, instead of “required”, the client apps are allowed to fall back to an unsecure connection which uses the local IP address of your server. For some reason though, this only works for the main media item, not trailers and other extras.)
Secure connections are set to “preferred” and rebind protection is off. It fails whether or not the client is on the same network.
Then it can still be an issue with DNS. Try using 1.1.1.1 or 8.8.8.8 as DNS server. See if it makes a difference.
No change.
Which Plex client type did you use when you encountered the above error message?
Both the web and the Android client.
Do you also have Cinema Trailers enabled? Please see release notes for PMS 1.43.1.10561
Please do the following;
Sorry for the delay, had to wait until I was free and the DVR wasn’t recording something. Hope this helps.
1.5 Mbps. Arrived at that through trial and error since it seems to be a good starting place and Automatically Adjust Quality works well.
Could you set that to Maximum and see if that helps with trailer playback?
No change.
Thanks for checking.
Just to be thorough, I also checked the LAN option just below that and got the same result.
