After successfully installing the ArcGIS Monitor 2025 agent on a DataStore server, ArcGIS monitor successfully detects the windows components. But there is an error when registering the relational database component "The server does not support SSL connections".
Exact issue with potential fix is here: https://support.esri.com/en-us/knowledge-base/error-arcgis-monitor-the-server-does-not-support-ssl-c...
changedbproperties --store relational --enablessl true
Still fails to register. The SSL certificate is valid on the DS server.
If the SSL property was disabled on your Relational Datastore and you just enabled it with the above command you will need to restart the ArcGIS Datastore Service on the server to complete this change before you can register this component with the ArcGIS Monitor Server.
