I'm upgrading Tableau server from 10.2 to 10.3.1 and my present installation has a primary node and 2 worker nodes. During the upgrade,tableau prompted me to upgrade my workers manually and after upgrading primary tableau is having trouble connecting to the worker nodes . the message i see is "worker xxxx is not responding". confirm that the worker is installed,running and configured with the computer name or IPv4.
I have configured the worker with IPv4 and also tried with machine name. i have also disabled the firewall on the worker.
