This problem has nothing to do with the QNAP upgrade. I already had this problem in firmware version 4.2.x and i got this problem in version 4.3.x too. As i already said, Plex is working fine but i am receiving the error posted above during a Plex upgrade.

Aha, now I understand this better. I have the same situation as you and I’ve never considered it to be a problem. For some reason, during any PMS installation (new or upgrade), QTS checks if PMS was started before it is actually started. But the fact is that PMS starts. Probably the installation script should wait a little before testing that PMS is active. So, for me, no problem other than the annoying QTS entry in the log (there are so many annoying things in logs, specially in the PMS log, that I no longer care).

Maybe @dane22 can take care to change the installation script when back from his vacation.

In my opinion it’s a false positive and has to be fixed. Every time i upgrade Plex i am getting two messages within the QNAP gui and i am receiving two mails containing the errors.

I did realize, that plex server has been started, but the info in the browser was misleading. If you try to log on your PMS using a IOS or Android device using the plex app, the server is shown and I was able to access it. I did then open the browser on the tablet and needed to allow for insecure connections. I was then able to connect to PMS and did then manage to change the network settings within the enhanced server settings. The key for me was to change the settings “secure network connections” from “required” to “preferred”. After deploying this change I was able to access my PMS on my QNAP TS-251+ and my PC’s with WIN7 and WIN10 again. SW-versions PMS 1.5.5.3684 / QTS 4.3.3.0154. Hope this might help. Regards

I just upgraded my TS451+ to 4.3.3.0154 and my Plex Server 1.5.3.3580 no longer starts. The log file shows the error “Plex Server hasn’t been enabled or started”. I manually stopped and restarted PMS and I am still unable to connect. PMS was working fine prior to the firmware update to the TS451+. I tried connecting via the android client and it also does not see the PMS.

I have the same problem. TS-269L Plex is not running with latest version.

Please read QNAP FAQ, specially Q20.

In order to be able to access it via Android, I had to upgrade to Plex Server 1.5.5.3634, which I have downloaded from plex.tv and manually install it. I did realize, that my solution which I found as a workaround could even be simplified. Instead of using http://192.168.x.x:32400/web, you could just use an https://192.168.x.x:32400/web you will then receive a notification, that there is a problem with the certificate of the site. If you accept to proceed, with the connection to your own server, because you know, that the certificate is self released, then you will be able to logon. You could then change the Settings, how I’ve outlined.

Solution

This is because the way QNAP checks if Plex is running is not sound as it’s simply just using the plex URL to check if the Plex app is running or not and if it gets a 404 (site not found) it thinks the Plex site/app/service is down. In my two cases, the Plex app was running fine, but QNAP was either using the wrong URL (needed HTTPS instead of HTTP) or because it couldn’t proceed to the site since the default browser would need to manually accept the site’s self signed certificate (one time).

First, QNAP uses the HTTP (not HTTPS) url to access the site, which is fine unless you checked the Plex server config setting to only allow secure connections which would require you to access the site with the URL prefix of https instead of http. QNAP doesn’t know this and tries to check if the app is running by using the http URL and it fails since it will only respond on https after that option is checked.
i.e.
Link that QNAP uses: “http://192.168.0.197:32400/web/index.html#”.
Link that you need to use to open the Plex server if you have the “Secure Connection Type” set to “Required”: “https://192.168.0.197:32400/web/index.html#

Second, after you click on the Plex icon within the QNAP webpage app, it’ll try to open the Plex site in the default browser and the browser may show a warning about the site not being secure due to an untrusted Plex site certificate. You’ll have to click thru this (“Proceed” text in Chrome) to have the browser accept the (self signed certificate) and go to the Plex site which is just a one time ordeal (unless you clear all your browser certificates).

Hope this helps!
