Getting "The communication with the agent launcher service failed." while running desktop flow in unattended mode

(1) ShareShare
ReportReport
Posted on by Rajasri 14

Hi all,

 

I have a scheduled power automate cloud flow which runs a desktop flow in unattended mode provided with a machine connection.

Sometimes, the desktop flow throws "The communication with the agent launcher service failed." error.

 

Can someone help me regarding this?

 

Thanks in advance.

    Sounds like you service "UIFlowAgentLauncherService" has stopped....
    Make sure it restarts in case it crashes.

    There are three services on the machine that runs the unattended job, that needs to be running.

    I have checked on the machine's Task Manager's services list. Didn't find those 3 services listed. Could you assist how to add them?

    I found those 3 services listed in TaskManager's services and all the three were running.

    But where they running when you got the error?

    Yes, they were running at that time.

    We're seeing this issue "consistently intermittently" if that makes any sense. 

    • All services are in running state on each machine
    • Restarting services has not resolved the issue
    • Rebooting the machine resolves

    Obviously having to reboot a machine meant to run unattended flows is not optimal.  Is there some bug or other machine setting that is impacting this?
