Fired when a SAP HANA system hasn't reported a PING alive

Hello Team,
We have setup the Azure Monitor for SAP Solution for HANA DB with HANA Provider.
Here the problem is that we get the alert for HANA DB unavailability even though HANA DB is up and running fine.
AMS is not able to PING to the server to get the DB status.
Can please assist to fix it.
Alert : Fired when a SAP HANA system hasn't reported a PING alive for the last 20 mins.
