We just purchased Desktop Central to replace SCCM, third party software patching system and our bomgar account.  I successfully have DC agents and MDM agents communication from internet through secure gateway to or DC server.  How do I make it so my IT team can use the DC Console to manage desktops?  I also would like them to be able to use the Android/iOS app.  When I try to access the console from a remote connection, it hits the sender however we just get a white screen in the browser.  When checking the logs, i can see the the machine I'm working from show up in the logs, but I seem to be getting a 400 or 404 error.  Is there and additional incoming port I need to have open in order for this to work?

Thanks for the help!
