UPNP Logs waking up NAS

Plex Media Server Metadata & Adding Files

I am facing the same issue.

Dear BigWheel,

Thanks for looking in to this. In the log files I get (with 192.168.1.1 being my internet router):

Jan 05, 2021 21:08:23.004 [0x7f9ef8875700] ERROR - SSDP: Error parsing device schema for http://192.168.1.1:45514/agent.xml

It seems plex scans devices on the network and the router doesn’t like it and resets the connection, which is logged by Plex. Is there any way of telling Plex not to scan that IP? Have you solved such an issue before?

I believe that it is this error log that prevents my system (QNAP-453D) from staying spun down. I have been in touch with QNAP and we have narrowed it down to Plex causing the spin up of the drives every ~5 mins. Every time I check the logs I will find above entry in the file. With Plex turned off, the device stays spun down (even over night).

It would be great if you could help me with this issue.

Thank you very much in advance for your help.

Best regards,

the only things to really turn off is Enable local network discovery (GDM) in network settings.

6

you might also check if your nas has UPNP enabled, and if so disable that.

all that network traffic is UPNP devices communicating with each other.

7

Thanks for the hint, but I had that already turned off after reading some other users comments.

8

Thanks for the hint, as with the GDM UPnP is turned off on the router (already for security reasons).

you can uncheck the logs in the server general settings and see if that helps avoid waking your nas?

Plex Web > settings > general > uncheck logging

it should be noted though, that plex server is designed for running 24/7 to provide access to you/your users.

maybe your nas has a schedule where it can shut down PMS at a specified time, then start it at a specified time?

10

What brand&model router do you have?

11

Thanks for the hint, just unchecked it and will observe over the next minutes.

Clearly, scheduling PMS (or manually turning it on and off) on the NAS is an option, but I see it as a last resort since I would like the availability.

12

maybe turn off DLNA in PMS as well if it is on.

13

It is a provider proprietary box called Salt Fiber Box (I’m based in Switzerland) delivering up to
10Gbps symmetric. https://fiber.salt.ch/de/home/equipment/fiber-box

Thanks, it is already off.

I’ve never been successful at this.

When Plex is running, there are quite a few reasons it will periodically read and write to the disks.

  • Any communication with Plex clients
  • Any network/UPnP/GDM activity
  • Any network interface state change
  • Periodic updates to MyPlex registration & certificates
  • Periodic database statistics logging
  • Periodic scheduled/Butler tasks

Logging and statistics can’t be fully disabled. And you shouldn’t disable all of the periodic tasks.

So:

  • You can fully stop Plex, with the obvious implication.
  • You can put the NAS in the garage or basement, so you don’t have to listen to it. :slight_smile:
  • You can move Logging and the Plex databases to an SSD, to keep the HDDs from spinning up. If you have a slot in the QNAP I recommend trying this.

Turning the debug logging off does not affect the spinning up.

bascially PMS is using SSDP to look for tuners and the like and it is not treating it differently than any other device on the LAN. the router is claiming to have a schema at a URL and then not giving an XML document at that URL.

I don’t know what setting in router would be there to not announce itself like that. the router may have it’s own DLNA server

usually ISP provided routers a pretty crappy

This!

Thanks for your reply. In fact, I am running the QNAP system (and all qpkg including PLEX) on SSD, however I believe once one disk is accessed, all drives will be spun up (seems to be a QNAP thing). How can I deliberately move the logging to the SSD drive?

I am fine with plex performing periodic task during the day (scheduled time slot), however I would like it to be quiet if I don’t use it for watching a film or listening to music in the evening as the NAS has to be located in the living room.

I agree with the “crappy routers” comment, however, would it perhaps be an option to make PLEX not look for a tuner at the location of the gateway?

21

possibly in the future. I’ll bring it up to folks but right now that is not possible
