If the first host screen (refer to Verifying the Application Connection) was not displayed when connecting to the host, check the following:
Do you have an internet connection?
Does your network security setting allow you to connect to external addresses using the Telnet protocol? (port 23)
Try to use Windows built-in Telnet command to connect to the host.
Make sure you have selected the correct device type and protocol in the ApplinX host definition.
Try to ping the host (10.20.91.201).
Check ApplinX Server log file (located in \log\gxlog.txt) for specific error messages.
