That's correct. I thought you would like to prevent existing clients who already reported to the ESMC server from connecting to it for certain time.

I'd suggest raising a support ticket with customer care and providing them with status.html and trace.log for a start. Beforehand, temporarily enable trace logging for agent by creating a dummy file traceall (without an extension) in the C:\ProgramData\ESET\RemoteAdministrator\Agent\EraAgentApplicationData\Logs folder and restart the agent service. After a short while, stop the service and delete the file traceall.
