need more details.
also, first you need to determine if the server is actually up and working or down, or if its a client can’t see it problem.
is the server on the android box, or is a separate device (pc or server or what) ?
does your server show up @ Plex ?
if it does not show up on on the link above, does it show up when you go straight to the server ip @ https://your.server.ip:32400/manage ?
is your client logged into the same plex account ?
you can setup a manual connection in the client in the settings > advanced > you will have to specify the correct ip etc
but this probably won’t help you if the server is down, or if the server is not allowing insecure connections, or connections without authentication.
edit: also, are you on ATT ? there is a routing outage going on which may be affecting you. if so see @ AT&T Fiber Internet Blocking Plex login
