The server "Media" does not allow secure connections

been having some issue with accessing PMS on QNAP, via apps. The latest is the message The server “Media” does not allow secure connections. If I do allow once it all works. I suppose I could do always allow, but I’d rather fix it on the qnap. PLEX has the Secured Connections set to Preffered.
Does anyone know what setting I need to change on the qnap?

Please don’t cross post!
