which interface do you have selected as your primary in the server’s network settings.

there seems to be lots of interface change notifications in log.

I’m using /etc/netplan for network settings. Here is the file print out:

network:
ethernets:
enp4s0:
dhcp4: no
addresses: [192.168.1.102/24]
gateway4: 192.168.1.1
nameservers:
addresses: [8.8.8.8,8.8.4.4]
version: 2

I’m running Owncloud and QBittorrent from the server both with remote connection and they have not had any issues.

Sorry I meant what do you have selected here? Try changing it to your 192.168.1.102 if not already.

I can’t see that. My server doesn’t show up at all.

If I may be of some assistance?

  1. Why are you using netplan ?
  2. Why not set the host manually and forget it ? Doing so is a one-time event.
  3. What was changed on the host? (Logs are not VERBOSE by default so it must have worked at some point)

The logs show the network going up and down (like a Yo-Yo). This is bad. PMS won’t work / respond when the network is changing even if nothing changed.

  1. Netplan wasn’t a specific choice. I’m running Ubuntu Server 20.04. It uses netplan by default. I am open to alternatives.
  2. I didn’t think anything had changed on the host. It was working great a week ago and then it disappeared. Before I wiped the install and started fresh I figured I would try and trouble shoot what was going on.
8

I also have 20.04.1

No “Netplan” specific use. I do use the Gnome NetworkManger. If it’s making the transfer underneath, fine.

[chuck@lizum netplan.513]$ ls
01-network-manager-all.yaml
[chuck@lizum netplan.514]$ cat 01-network-manager-all.yaml 
# Let NetworkManager manage all devices on this system
network:
  version: 2
  renderer: NetworkManager
[chuck@lizum netplan.515]$

Setting up the hostname and setting its IP in /etc/hosts will achieve the same thing.

But, before even diving into all that,

What happens if you

  1. Sign out of Plex/web (upper right corner avatar)
  2. Open Plex via the loopback (which is recommended when you are seated at the host - or SSH tunneling into it )

What does systemctl status plexmediaserver show?

Can you obtain the tar.gz of the Logs directory ?

Is this a native package, docker, or snap installation?

  1. Loopback address (127.0.0.1:32400) I get a “This site can’t be reached” message. I tried with my firewall off and on and got the same message

  1. Please turn VERBOSE logging off again. It serves no purpose other than make our lives tougher (too much info) except for specific cases. The default “DEBUG” is more than enough. (Verbose generates about 40 lines of output for every mouse click or data packet – complete waste)

  2. Your network, whether a physical cabling or how it’s configured, is an absolute MESS.

Plex cannnot and will not operate this way because , from its perspective, the network adapters are changing. Every time the adapters change, it must

  1. Stop what its doing
  2. Reset / restart all the network sockets (ports to talk to it)
  3. Setup again to listen
  4. Restart internal tasks.

This is a configuration error either

  1. In your Linux itself (( I assert you do not need direct manipulation through netplan – you’re overthinking it ))
  2. You have DHCP and the DHCP server is refreshing the lease every 60 seconds.
