Please check C:\ProgramData\ESET\RemoteAdministrator\Agent\EraAgentApplicationData\Logs\status.html and trace.log for possible errors on one of the troublesome clients.

Please check certificate details:

Hostname does not match any supported record in certificate SubjectAltName extension (eset.abc.local)

I  assume that you entered eset.abc.local as the host and this hostname is not accessible from the client. You can create a new agent certificate with an asterisk in the host field and reinstall agent (manually via a server-assisted installation or by exporting a new agent live installer):

still no luck with this also.

Please post the current status.html from the client to see what has changed.

Peer certificate may be valid but cannot be verified on this machine.

Have you recently changed the CA certificate? Does any of the machines still report to the ESMC alright? If no machine is able to connect, I'd recommend:
1, generating new peer certificates
2, generating a fresh live agent installers and deploying it on the clients (you can install agent manually on one machine and use server-assisted installation to see if the issue goes away then)

In this case, most relevant error seems to be the last one:

Quote

Hostname does not match any supported record in certificate SubjectAltName

which is reaso why AGENT is rejecting SERVER's certificate. Problem is that AGENT is trying to connect to hostname that is not "signed" in SERVER's certificate.

Other errors indicate also that there is missing CA certificate for AGENT's certificate itself, but that is not fatal problem.

Solution would be to create new ESMC peer certificate, that signs all used hostnames/IP addresses, and is signed by CA certificate trusted by AGENTs. Once properly set in ESMC's configuration, AGENTs should start to connect.
