Hi,
Verify database connectivity using below Symantec article.

or
Need to check the permisions where we have installed Symantec Endpoint Protection Manager.
- Domain account which has been used to access the SQL database should have "Local Administrator" rights on the Server where we have installed Symantec Endpoint Protection Manager console .
For the remote database connections that use the Windows Authentication mode, we must be aware of the following requirements:
- For deployments in an Active Directory environment, the Symantec Endpoint Protection Manager and SQL Server must be located in the same Windows domain.
- For deployments in a Workgroup environment, the Windows account credentials must be the same for the local computers and the remote computers.
