Error creating a RDP session for half a day

Hi everyone,

We have bots in production that have run for several months without any particular deployment problem 

On this week-end for half a day we had a systematic deployment error “An unexpected problem occurred” on both production VMs that we can’t explain. There is no information about updates or maintenance on AWS side. Moreover on a third VM not linked with that project, bots ran correctly.

The error solved itself alone and at the same time bots started running correctly on both VMs.

It was during the week-end and to my knowledge nobody did connection, admin action or maintenance on the VMs

Do you have an idea on what could be the cause of this problem?
