QNAP NAS Plex not listening on 32400 after re-installation

Plex Media Server NAS & Devices
1

Server Version#: 1.16 & 1.18

This is puzzling. I have here a QNAP TS-563 that has been running Plex happily for a couple of years. A few days back I did a factory reset and rebuilt it, and now Plex has gone all sulky and deaf.

The package installs and runs successfully, but I get no socket created on port 32400, so I cannot load the admin web page to set it up.

I’ve tried v1.16 from the QNAP store, and v1.18 downloaded from this site, with the same result. I’ve combed through the log files and can’t see any really obvious failures, in fact at one point the package is communicating with itself on 32400 happily, but that port doesn’t stay open long enough for me to connect to it.

Any ideas where to go next for diagnosing the problem? I’m happy to poke around at the command line on the QNAP, and can upload any logs anyone wants to look at.

Just for fun, I tried installing Plex on the little backup TS-431P NAS that is right next door to the TS-563, both physically and logically, and it worked fine first time. But I don’t want to run Plex on that box, it’s there purely to receive backup copies of my data overnight.

That would be step 1

OK, I’ve uploaded them now.

Plex DLNA Server.log (9.3 KB) Plex Media Server.log (350.2 KB) Plex Tuner Service.log (2.8 KB)

According to PMS log, all is fine…

From a terminal, type: ps aux|grep Plex and show the output

7

Also netstat -na | grep "32400"

Ah, that’s interesting, Plex has bound itself to IPv6 exclusively. Give me a second, I’ll try disabling IPv6 on the NAS.

Side note:
Your PMS is getting old :wink:

v1.16.6.1592-b9d49bdb7

Yes, I’ll upgrade it to v1.18 once I have it working. v1.16 is the version currently listed in the QNAP App Centre, and it’s easier just to click on that once I had established that both versions behaved the same.

I’m having trouble disabling IPv6 on the QNAP - it’s disabled on both network interfaces now, yet Plex is still binding to an IPv6 address, somehow. Is there a way to configure Plex to favour IPv4, from the NAS command-line?

11

/share/CACHEDEV1_DATA/.qpkg/PlexMediaServer/Library/Plex Media Server/Preferences.xml

Has a setting that should be: EnableIPv6="0"

After changing, restart PMS

And remember to backup your xml file before editing :wink:

12

OK, thanks. That’s got it binding to IPv4, but I’m still getting no connection from the browser, which reports that the connection was closed by the NAS box, with no pause. I can see the socket connection is being made, as there are multiple connections in TIME_WAIT state from my PC (192.168.100.61)

(I’ve installed v1.18 now, by the way, since we’re making progress.)

15

Ah, talking of progress - I’m in.

The closed connections were in response to https://192.168.100.21:32400/web, which is the link from the Plex web page. Dropping back to a normal http connection works OK.

Is there a way to enable https on the Plex process?

16

And now, having completed the setup, https is working, so I think I’m there.

Thanks for all your assistance!

Fair enough. I don’t recall tripping over that before, but perhaps I did and jut don’t remember it.
