Without relay, it doesn’t:
“Unable to connect securely.”
When I change “Secure connections” from prefered to required:
“currently unavailable”
I ran out of ideas. My infrastructure is quite simple.
Qnap TS-253B right behind the router
Plex server app qpkg (continuously updated from plex.tv)
Router: FritzBox 7590 AX (manual Port forwarding TCP/32400 (no UPnP) to my Qnap NAS & exception from DNS rebinding for “plex.direct”
No jumbo frames
*edit: Ive found this in the log:

So recommend you move interfaces 16, 17, 18 to other IP Nets, and then restart your QNAP
Also it looks like you are using QNAP’s myqnapcloud.com which is not supported
Getting that to work is not something I’ve tried myself, and would req. that you add valid custom certs to PMS, as well as specify the custom domain/host it should be registered as
Recommend you for a start only use normal Plex access, ( https://app.plex.tv ) and when working, you can start to look into the QNAP Cloud stuff, if needed
I’ve removed all IP addresses from interfaces 16, 17 an 18.
Since your question regarding app.plex.tv I don’t use myqnapcloud.com anymore. So I don’t think that a custom certificate is not needed.
Unfortunatelly it still doesn’t work.
I checked it. Port 32401 is a docker container which was coexisting for while.
Im pretty sure, that the forwarding to the Plex Qnap app always was 32400.
