There could be several reasons if SQL Server is unable to connect to the local server. Here are some common troubleshooting methods:

  1. Check if the SQL Server service is running: Open the Windows Service Manager and verify if the SQL Server service has been started. If the service is not running, try starting it.
  2. Check if the SQL Server instance name is correct: specify the correct SQL Server instance name in the connection string. By default, the SQL Server instance name is “MSSQLSERVER,” but you can also specify a different name for the instance.
  3. Check SQL Server Configuration Manager settings: Open SQL Server Configuration Manager, ensure that the TCP/IP protocol is enabled, and that the port number is set correctly. By default, SQL Server uses port 1433.
  4. Check the firewall settings: If the firewall on your computer is enabled, it may be blocking SQL Server connections. In the firewall settings, make sure to allow incoming SQL Server connections.
  5. Check the SQL Server authentication mode: Specify the correct authentication mode in the connection string. If SQL Server is configured to use Windows authentication, provide the credentials of a Windows user. If configured to use SQL Server authentication, provide the SQL Server login name and password.
  6. Check network connection: Verify if the network connection is working properly. Try connecting to the SQL Server using other network devices, such as through a local network or via VPN connection.

If the above solutions still do not resolve the issue, try reinstalling SQL Server or contact the SQL Server support team for further assistance.
