    Hi Nadir Husain,

    Firewall systems help prevent unauthorized access to computer resources. If a firewall is turned on but not correctly configured, attempts to connect to SQL Server might be blocked.

    To access an instance of the SQL Server through a firewall, you must configure the firewall on the computer that is running SQL Server.

    Try to configure firewall to allow access sql server port 1433.

    You could refer below article:

    Configure the Windows Firewall to Allow SQL Server Access

    Jalpa.
