My problem started when when I installed and started Plex. If you click on the Qnap app Plex icon where it says "Open", it opens another browser tab and the config screen should come up. Well instead I get the dreaded "Secure Connection Failed" webpage and no "Advanced" button to accept the webpage as "good". Searching for hours found some suggestions but nothing worked for me although the comments were pointing me to a Qnap HTTPS issue.
I got around this and into the Plex config by removing the "s" from "https:" in the Plex' webpage URL but I thought that is annoying, there had to be a better way. I played around with the Qnap settings and I found something. My original settings under Control Panel > System > General Settings > System Administration had "Enable secure connection (HTTPS)" enabled and "Force secure connection (HTTPS) only" enabled as well. Safety first, right? Only when I DISABLE both, THEN trying to bring up the Plex config webpage resulted in a URL WITHOUT the "s", only "http:" and it worked. Note: If you disable the "Enable secure connection (HTTPS)" option you must use "http:" instead of "https:" to access your Qnap NAS admin screen!
So since I do not wish to access the Qnap NAS without "https:", I will need to remember to remove the unused "s" in the "https:" of the Plex config screen the Qnap Plex app attempts to send me to. Qnap should either supply the certificate (if that's the actual problem) or make the Qnap app URL's correctly. Please.
