Upgrade 20.4.3 to 21.4

I am trying to upgrade on-prem orchestrator to 20.4.3 to 21.4.
I used UiPathOrchestrator.msi. After the upgrade orchestrator, I am getting this error:

There is not any proper document about 21.4 upgrade in document center.
Does anyone face this issue? Are there any manual steps after the upgrade?

Hi @ekaraoglu ! Are you using Orchestrator Enterprise ? If yes, you can open a ticket here and they will answer you quickly

We opened ticket on 4th June. They do not understand either. I will try to ask for support again tomorrow.

Sorry :pensive:
Check if you can find something on the windows event viewer, we never know
