Symptoms

Some UI flows are failing intermittently when running as part of a flow on a Gateway Cluster.

Verifying issue

If flow runs are intermittently failing when running on a Gateway Cluster, it's possible that some members of the cluster may be in a bad state. Here are a few steps you can take to find whether specific machines should be recovered, and if so, which ones:

  1. Go to the Connections pages under Data/ in the left pane

  2. Find the desktop flows connection targeting the cluster you're interested in: Filter for desktop flows, and on the connection details page, check out the Gateway field:

  3. Go to the Flows using this connection.

  4. Identify the list of desktop flows running within the list of Flows.

  5. Go on the desktop flow details page, and checkout the run history, taking note of the failing runs and the corresponding machine name:

  6. Verify all desktop flows runs. If the failures are all happening on the same machine, this machine might be in a bad state and need recovery.

Solving steps

Make sure the machine is online, and reinstall the On-Premises Data Gateway and the desktop flows package if needed.
