Credentials cannot be set using an offline data gateway. Launch Data Management Gateway Configuration Manager on the gateway machine and confirm that the "Service status" is "Started", "Gateway key status" is "Registered", and the status bar shows "Connected to Data Management Gateway Cloud Service". If not, check Windows Event Log on the gateway machine for detailed information. Reopen CREDENTIALS blade to set credentials when the data gateway is online.
