Quick check in the event of unsuccessful connection attempt to the gateway

You should make the following checks if the connection to the selected gateway computer is not successful. (You get the message „not connected" in the Communication Parameters dialog behind the gateway server address in the field Channels):

  • Has the gateway server been started (the three-color symbol appears in the bottom right portion of the toolbar) ?

  • Is the IP address that you entered in the 'Gateway: Communication Parameters' dialog really that of the computer on which the gateway is running ? (use „ping" to check)

  • Is the TCP/IP connection working locally? The error may possibly lie with TCP/IP.
