RE: could not connect to server
This error occurs normally when your device could reach the ipaddress/port of the machine. May be below reasons
1. You may be in a external wireless n/w or 3G and trying to access your secured n/w. Try pinging to this IP address from your device.
2. Port you are trying to connect may different than the rdp listening port.
You can run the PocketCloud diagnostics in the server to detect any server configuration issue. Launch diagnostics from PocketCloud tray icon
