Plex restarts a old dead IP address
Plex is broadcasting an old ip address from my NAS. I uninstall, wipe the plex directories and users from my NAS and sign out of plex.tv. the old ip address goes away. I reinstall, and the old address comes back on my NAS; before I even log into the new plex server.
i had plex running a couple years on my synology nas, with no problem, watching my Vizio smart app. I got a new router, and a new address, moving from .110 subnet to a .255 subnet. Then the Vizio couldn't find the NAS plex because, although the new .254 PMS address was there, so was the old plex.110 address. When i stop PMS, both disappear, when i start PMS they come back (seen in a netstat -a). The vizio gets confused if there are 2 servers and fails. I can get remote to connect over the internet, but it wont stream video.
How do I get the NAS Plex to forget this old .110 forever?
