Just installed and configured and everything is running fine... apart from Alexa, the one part I was after...
Internally on my network, all good.
Router configured with port forwarding
Plex web app shows as configured and available
Accessing web interface from an external device works fine.
Alexa says 'your server is online, but remote access is disabled or the server is taking too long to respond'
Any ideas what else I can check to get this working?
