Plex Server inaccessible with LG TV nor Ipone

 I recently had access issue to my Plex server (running on Linux).  It was fine sometime ago, but lately everytime I tried to access it from my LG TV or my phone, they said the server was offline. I'd followed various instructions and troubleshooting I found on the Internet with no luck.  Here is the list of steps I did:

  • Ensure no VPN running on all devices and server
  • Select "Preferred" for secure connection
  • Added my private subnet in the "List of IP addresses and networks that are allowed without auth"
  • Upgrade the Plex server to the latest
  • Restart the server (e.g., "sudo service plexmediaserver restart")
  • Verify I am able to access the server through its IP (e.g, http://192.168.1.103:32400)
  • Enable DLNA server
  • Revert the Plex on TV to last publicly available version
  • Power down TV, wait 2 minutes and turn it back on

Turned out it was due to IPv6 connection was enabled on the Plex server! Once I disabled it, now I could watch my movies or stream my music to other devices.  My LG TV apparently did not support IPv6 yet.
