[Unable to connect to the Authentication Server]

I got this working.. Looks like I did not save the Login after adding the IP address for the server.

 

[Unable to connect to the Authentication Server]

I purchased and setup an Atavism Cloud Server and am trying to test out the Demo.  When I go to register I get "Unable to connect to Authentication Server." 

I have made sure the server is running in the Atavism Stand Alone Editor.

I would assume the ports are open on the server side when using the Atavism Cloud Server. Do all clients need to change their firewall settings to connect?

I have set the IP address in the Unity Editor for the Login Page to the IP address provided for my Atavism Cloud Server.

Thank you for your help.
