Communication link failure trying to access Studio

On one HealthShare servers (RH Linux, 2017.1.1), I am not able to login to Studio for this server. When I select the server connection from the notification tray icon, choosing Remote System Access, Studio, then the server, the error I getting is:

Unable to log on to server {Server Name}

Communication link failure

I've tried using both DNS name and IP address, same result. Using Atelier, I am able to connect to the server using the same DNS name and Web Server Port that I'm trying in Studio.
