Server Cant Be Found



Apologies for the minimum information here, but this is all I have.

I have just signed up for Plex Pass as it seems like exactly what I want. A platform to store all my videos on and backed up on dropbox) and access from around the world on my fire stick.

However, having installed the Plex Media Server on my Mac, and run it - the Media Server says it can't find a server. Also, despite linking my Dropbox (which was movies in it) - there is no media showing as available.

I hate to bin this as it has taken so long to find something that might match my requirements, but if it won't even start running, why would anyone bother paying for it?

Any advice on getting the server to actually run and set up a shared folder would be well appreciated.
