I had an issue where clicking on the plex shortcut would take me to an old IP address.

The cause was that I had configured the LAN1 connection with 10.0.0.68 (eth0) and then moved home and plugged the DS415+ in using the LAN2 (eth1) interface.

The Plex cgi that returns the interface address returns the eth0 address (assuming that we always plug in LAN1)

My work-a-round is to add a query to check which link is in an up state to the "/var/packages/Plex Media Server/target/dsm_config/plex/plex.cgi" file. Here is my version:

Note: Every time Plex updates it will overwrite the change.
