Error when attempting to connect to a device: "Could not connect to the Automation Device acquired using DAMachine, Error calling Desktop Automation service: Caught exception. Error getaddrinfo ENOTFOUND DAMachine DAMachine: 49998 at ernoException (dns.js:50:10) at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:92:26)"



Name resolution issue after device operating system is upgraded.



  1. Reconfigure DAS to use single-user mode and specify the IP address for the Host field. Restart DAS.
  2. From Design Studio, recreated the device using a direct connection, not Management Console.
  3. Retest to verify successful connection.

You can then create a device mapping in Management Console after finished development in DS using single user mode. Change DAS back to Management Console mode access and restart.
