Local web app does not find local PMS

server-freebsd

#1

I just installed PMS in a jail via ports. I connected to 192.168.1.3:32400 and logged in to my Plex account. The web app says: A server could not be found. Download and install Plex Media Server, and it will appear here.
I've searched Google and the forums but the FAQ (https://support.plex.tv/articles/204604227-why-can-t-the-plex-app-find-or-connect-to-my-plex-media-server/) is useless. It is the local web app (127.0.0.1:32400) that does not find the PMS that is itself.
AFAIK all processes are running:

Any ideas why PMS does not find itself???
