I recently had a problem with my robots running on a remote desktop connection where i encountered the error message displayed in the title. I thought it would be nice to share my experience in solving the issue in case anyone else enounter the same problem.
In my case, all i had to do was restart the server a few times before the robots could connect and start running again.
It wasnt worse than that, but incase anyone else encountered this problem i thought it might be good to post a possible solution here.
