    Are you have to permit your account sccm admin on the local group server database?
    And make sure you add permission also in your database for your sccm account adm

    Did you set 1433 on console config SQL and restart all SQL services. And check your database service start?

    Try logging in as the local administrator. And reperform connection to DB if it goes well I think this is an SPN issue.
    If it does, download a Kerberos ConfigMgr on the SQL server and fix the spn.

    You need to enable named pipes on the SQL server and ensure that the firewall and nsg allow access.

    Please check your firewall, make sure you disable the firewall on Server Database and try again.

    Can you try ping from the server database to server MECM?
    Its replay?
