Can't claim server - ipv6 issue?

paxinos · May 2, 2020, 7:07pm

Server Version#:1.19.3.2740

Seems Plex is listening with IPv6 on port 32400. If I connect to port 32401 I get the plex app - but doesn’t have any place to ‘claim’ the server. And trying to load http://localhost:32400/ (using.a browser on the server) results in a timeout .

PMS Logs in a zip please

paxinos · May 2, 2020, 7:29pm

can’t access through the portal - no other plex servers… so which files from Linux would you like?

dane22 · May 2, 2020, 7:32pm

Zip the entire PMS log directory

The server was working for awhile. It stopped working. I updated the installation - that didn’t help. So I deleted and reloaded. Still didn’t work. And that’s when I noticed it was listening on the IPv6 address…

Are you running it in a docker?

And puzzled here…

The 5 PMS logs shows, that all from today, shows different interfaces every time?

Above looks good, with the primary set to the onboard nic, but you went away from that?

paxinos · May 2, 2020, 8:14pm

I’ve been trying various permutations without success. Which permutation do you suggest I stick with?

This is what I have right now - with the wifi link.

With this configuration:

http://localhost:32400/web - timeout
http://localhost:32401/web - plex app without local server or ability to ‘claim’

Don’t use Wifi link for the server, stick with the one I mentioned above

Ok, I turned of the WiFi Chip… purely on ethernet.

I then restarted plex and still have the same problem (using a browser on the server) -

http://localhost:32400/web - timeout
http://localhost:32401/web - plex app without local server or ability to ‘claim’

Logs please, again

Seems good, now two Q’s for you:

When browsing towards http://192.168.5.185:32400/identity does the xml that shows in your browser has an entry named claimed and if so, is it 0 or 1?
are you browsing towards PMS directly on the server, or from a workstation, and if so, what’s the IP address of that workstation?

paxinos · May 2, 2020, 10:36pm

I am running Firefox on the server.

I get a timeout when going to that url.

dane22 · May 2, 2020, 10:38pm

Huh…

It’s an IP loaded on that same box?

What happens, if you try http://127.0.0.1:32400/identity ?

dane22 · May 2, 2020, 10:38pm

And timeout might be firewall related!

dane22 · May 2, 2020, 10:39pm

And this Q still needs to be answered!

paxinos · May 2, 2020, 11:03pm

Plex is not running inside docker.

No firewall.

Obviously docker has a bunch of iptables. I’ll slog through it again but I didn’t see anything obvious. Btw, this problem happens even when docker wasn’t running so iptables would have been empty. I’ve rebooted the machine multiple times this afternoon. With and without docker starting.

Remember, the timeout is part of my original post. Hasn’t changed.

The same machine is running Kubernetes and I’ve been working on KubeFlow in between working on this issue

Hmm. It would be interesting to get Plex in docker. But that would be after getting it running again. I can setup multus-cni which should make running plex in kubernetes pretty easy - just give the container it’s own LAN IP address

paxinos · May 2, 2020, 11:07pm

Yes. Timeout when going to localhost as well.

And 192.168.5.185 is the machine’s address on its Ethernet.

I get a response from port 32401. But it’s obviously not the right server.

The only thing I’ve noticed is 32400 is running on tcp6. Unfortunately I haven’t played around much with IPv6 to know what difference that makes.

Btw, fwiw, I’m running on Ubuntu 18.04

dane22 · May 2, 2020, 11:10pm

Hmmm…

According to the logs, PMS is running, and is listening to 192.168.1.185 which is the servers own interface, and yet it’s not possible to browse it?

It’s NOT IPV6 related, but IPV4 related !

If your PMS server is running, and reports it’s bound and listning to port 32400 on both loopback as well as the IPV4 address, and you can’t reach it, it’s something else!

Can you, just to make sure it’s not a browser issue, try and install Chrome on the box?

paxinos · May 2, 2020, 11:51pm

I think there is a difference between what you are seeing in the logs and what I’m seeing in netstat ?

See the results below using curl

I live in Linux network. Especially recently. This has me stumped.
