Multiple Plex Servers (MacOS) on same NAT router

Hi Guys, So I’ve my main house Plex server which has all the Films and TV on it working fine on my old Mac Mini.
But now I want to have a second for my iMac for my Go Pro recordings… and when I enable the second it comes up and replaces the first. It seems that I can only see the last Plex Server that registered itself.
So when I from all my Plex Clients I can only see the last server.

I’ve tried disabling the remote access/configuring it to use a different port nothing I’ve done makes any difference.

How do I have two servers working at the same time?

I have three servers running Each on it own dedicated machine, Each server must have its own ip address…

Thanks Tumpy I can confirm that they both have their own IP address and physical addresses.

Well I had another go at it. Seems there are some parameters like MachineIdentifer in the defaults which are identical between the two servers. So I suspect I must have restored from backup of the other. I’ve also confirmed that if I start a virgin machine that it works perfectly.

Tried clearing the defaults and restarting but for some strange reason they just get restored. So something is getting cached.

Still in the right direction will crack it soon…

Yes cracked it… Seems even if you use the command ‘defaults delete com.plexapp.plexmediaserver’ the cfprefsd (system daemon) still retains a copy and even a reboot does not clear them.

However deleting them and then killing the cfprefsd worked fine. So this is what I did:-

defaults delete com.plexapp.plexmediaserver
launchctl stop com.apple.cfprefsd.xpc.agent
pkill cfprefsd
launchctl start com.apple.cfprefsd.xpc.agent

Then when I ran Plex Server it started with new Identifiers.
