You have successfully signed your server in to Plex, but we were unable to reach it from outside your network.
If you would like to enable this now, you will need to configure your router or firewall to allow Plex to contact your server. Please refer to our Connecting a Server article for more information.
You need to have your server connected to plex.tv to use the server from the xbox one application. Please let us know if you still see problems after following the steps in https://support.plex.tv/hc/en-us/articles/200484543. Thanks!
