Hey Guys!

We are currently running a SCOM 2019 with ACS collector.
I got a couple of forwarders in DMZ that have stopped reporting.
The SCOM Agent is green and the alerts is working as normal.
I've double checked all the certificates.
Ports are all open.

Any help is appriciated.

Here is my logs

    Hi,

    I would say that you have an issue with authentication (certificates), but this is impossible if you have a "green" status and those agents are alerting. Did you try restarting the relevant services?
    Are there any related events in the event log on this system or on the Management Server it reports to?
    The error "0x00002746" is a ConnectionReset Socket error and points to a problem with the communication (either because of networking issues, or because of authentication problems). Maybe that will help you find the culprit.

    Thanks and Regards,
    Stoyan

    Very odd issue.

    I re-created all certificates for our DMZ machines and imported it again.
    Connection successful.
