Yesterday the conneciton state monitor triggered in our production instance of SCOM. We are on 2019 U3 and have the 10.1.100.0 Microsoft 365 MP in place. this has been working for a couple of weeks now.
Going back into the wizard to setup the watcher running the synthetic test shows successful. I also see event ID 910 which shows PortalLogin
Success: Connected.
but the alert has this context
Authentication message:
Endpoint message: Connection to EndPoint Service failed
How can I troubleshoot this?
running this from the watcher is successful
