SessionCreationError - Cannot create new session to execute unattended run

(2) ShareShare
ReportReport
Posted on by 2
I am getting 'SessionCreationError - Cannot create new session to execute unattended run'.
 
  • This error occurs intermittently and randomly, without changing configuration.
  • The error occurs in about 30 secs to 1 min of running the 'Run Desktop Flow' Action. 
  • I have no problems when running in attended mode.
  • I have tried expanding the 'SessionCreationTimeout' (https://learn.microsoft.com/en-us/troubleshoot/power-platform/power-automate/desktop-flows/sessioncreationtimeout-error-code)
  • I followed the steps in https://learn.microsoft.com/en-us/troubleshoot/power-platform/power-automate/desktop-flows/troubleshoot-session-creation-errrors
  • The account I am using is the same I use when running attended.
  • I can connect with the same credentials to the VM via Remote Desktop Protocol.
  • I tried restarting the computer before, logging out and making sure no other user in logged in the Virtual Machine.
  • I tried in a different Virtual Machine with the same results.
  • It also fails when running with a Scheduler trigger. 
  • I checked the Power Automate services and they seem to work fine in the computer. 
  • I checked for any Firewall or antivirus blockade.
  • I assigned the proper "Power Automate Process" licence to the environment.
  • The machine is assigned to the environment and it shows 'Connected' every time in the app. 
  • I tried with different configurations in Power Automate app.
  • I updated to the last Power Automate Desktop versión (currently 2.48.153.24261)
     
  • The most strage thing is that the issue happens randomly (about 4 of 5 executions).
If anyone is facing the same problem or has solved it, I will appreciate your suggestions.
Thanks

    I am getting this error intermittently on my environment also. So far today 0.6% of desktop flow runs have failed with the session creation error. Seems to be becoming worse as time goes by.
