An error has occurred in Orchestrator

All my Unattended robots are showing status as “Disconnected” and Studio robots are showing status as “Unresponsive”.
I am not able to create or delete any robot from the orchestrator, it gives "An error has occurred’ error.
Also, I am not able to connect the robots to the orchestrator from the machine it gives "An error has occurred’ error.

I followed the steps mentioned in the link but still, nothing happened.

I checked the event log on the orchestrator server it shows this error.

@loginerror can you please help, its urgent!!
