Session Creation Error

Posted on by jackhart6376

I have a lot of different flows running unattended on a few remote desktops. Starting a couple weeks ago, I am constantly getting a session creation error. It is never the same flow that does it. After this session creation error, every flow after will not run, getting the error No Candidate Machine. Once I go in and reboot the server, everything works again without issue until the next session creation error. Any help will be appreciated

Seems like your machine connection is breaking all the time. Before you run something in unattended mode and make sure your targeted VM is added to power automate cloud and shows connected in machines tab.

I am experiencing the same across multiple environments and multiple Azure virtual machines. It started around the same time you referenced. I have had to log into the machine in the middle of the night just to restart it so it will run successfully. Anyone else experiencing this? @Deenuji your response is helpful and something I am doing on a regular basis. I've even re-created machine connectons. It is a failure either in Power Automate or the Azure virtual machines. Looking for some help / ideas. I have been using Power Automate in Unattended mode on Azure virtual machines for over 18 months without issue until now.

We had the issue at my workplace, starting same time as this post. Looking in Event Viewer, showed a DCOM warning around same time of the session error. After loads of fixing rights, just to eliminate the warning, the error persisted.

@Deenuji suggestion of checking they are connected before runs are good, but in this case never the reason for the error where I work. But after a restart of the server, we run on some hosted machines at a local datacenter at the moment, it has run flawlessly ever since.

All I can really tell, is that I just updated to the 2.45 version just before it started happening, and the one restart seemed to have done it for us so far.
