Sever could never be found.

Hello.

I recently download Plex media server and every time I try to load the sever it never reaches any server. I don't have much option either to try and fix the problem.

I get this message too:

_No soup for you!

The server you're trying to access doesn't want to let you in. Make sure you're signed in as a user with access to this server.
_

In setting I only have General, Debug and Player.

Please let me know what I should do to set up the server on my Mac.

Thank you.
