Setup two Plex servers on two different Synology NAS

[manuxi]

Hi!
First of all I’d like to say that Plex works since at least 5-6 years now in my local network. Now I’d bought a new Synology NAS DS1819+ and moved the installation from my old Synology NAS as described here: https://support.plex.tv/articles/201370363-move-an-install-to-another-system/. It works fine (although the configuration folder was very large ~ over 50GB). After successful test of the new installation I’ve tried to get both of the pms to run, but with no success. I can only see one pms (seems to be the one with I logged in latest).
My router is set up with port forwarding as described here (Section Manual Port Forwards for Multiple Servers): https://support.plex.tv/articles/200931138-troubleshooting-remote-access/ but with no luck. My setup:
Old server: 10.0.1.1:32400 - external port 32401
New server: 10.0.1.2:32400 - external port 32402
Using PlexMediaServer-1.14.1.5488-cc260c476-x86_64

Both servers tell me that they are sucessfully connected with remote access. But I see only one server.

I tried loggin out and on, hit the retry button for both pms, stopped pms on either old or new server. Everything several times, but getting tired now.

Is there something I’ve missed?

Thank you for your help,
Manu

If you copied the preferences.xml from the old NAS to the new one, you have practically “cloned” your server.
Which then means that neither plex.tv, nor your clients can really tell one NAS from the other.
You need to stop the server on one of the devices and then delete a few of the values from the preferences.xml
They will get recreated upon the next start. But this time with different values, so the two devices are distinguishable again.

Thnak you very much Otto! I removed every value which had something to do with an id; now it seems to work. Great!
