Re-install PMS but cannot Claim Server, so no access from devices

Plex Media Server NAS & Devices
1

Server Version#: PMS Version 1.14.1.5488
Player Version#: web client

Hi, Newbie (in terms of knowledge at least!).

Struggling with “Claim Server” and can’t get past it…

My home router decided to change subnet yesterday (and external IP) and so I restarted my NAS which came up fine on the new subnet, but not my Plex Media Server - web client couldn’t find server.

I followed this article (QNAP Plex Media Server - Server not found? and followed ChuckPA’s excellent advice by deleting prefences.xml, re-installing and going through the setup wizard without creating new libraries. I now see my Plex library via the web client (http://192.168.10.117:32400/web/index.html#!/settings/server/3d287dc7ae16ad86b0d30be750a30ac47af2270d/settings/general),

but I’m stuck here unable to Claim Server:

When I press Claim Server, the button presses, but nothing happens, it just stays at the same screen, no error, no progress. When I try to access the Plex Server from another device (Samsung TV in the same network) it can’t find the server (I guess that is what Claiming achieves).

The comment in the screen shot advising to update to latest - I did that, even though I already was on latest, and it just comes up the same again. I chose the 64 bit version as I’m on QTS 4.3.6.0805 build 20181228 on my QNAP TS-251 and the advice on the download site was to use 64 bit version of PMS if I’m on Intel chipset QNAP and running QTS 4.3 or above.

I’ve attached some logs (not sure they are the right ones, please advise if not)

Hope someone can make some sense of my rambling troubles…

Check default route on your QNAP network settings, since it looks like it can’t access the internet?

From the logs:

Jan 31, 2019 09:50:26.309 [0x7f0df8d11700] ERROR - NAT: PMP, map, couldn't initialize: -3:Unable to get Gateway

thanks dane22, sounds like a good shout…I can see the routing table in QNAP NAS is

Destination Netmask Gateway Metric Interface
192.168.10.0 255.255.255.0 0.0.0.0 0 Adapter 2

which doesn’t look right, even at my level of knowledge…
Found the “System Default Gateway” setting and set it to “Auto Select” as it somehow was on manual with no data. Now the routing table is a healthier looking:

Destination Netmask Gateway Metric Interface
default 0.0.0.0 192.168.10.1 100 Adapter 2
192.168.10.0 255.255.255.0 0.0.0.0 0 Adapter 2

and the gateway matches my router IP.

More importantly, after stopping PMS, deleting preferences xml and re-installing PMS, it’s all working beautifully again.

Many thanks dane22, much appreciated!!!

Cheers
Iain
