Add on the Microsoft SQL database the permission for the server as below:
CREATE LOGIN ['CA\masru02$] FROM WINDOWS;
CREATE USER ['CA\masru02$] FOR LOGIN ['CA\masru02$]
ALTER ROLE [TargetServersRole] ADD MEMBER ['CA\masru02$]
Add to primary server, HA hub and UMP portal
Or if you don't want to add this you must open the Nimsoft Robot Watcher go to Log On, choose the "this account" and choose the domain user that has the SA permission on the database.
The HA data_engine and also the wasp probe will always read and write information on the Microsoft SQL database.
