Connect to SQL Server Database Engine using SQL Server Authentication - error

There could be several reasons why you are unable to connect to the SQL Server 2019 database engine using SSMS 19.0.2. Here are some steps you can try to troubleshoot the issue:

1. Check if the SQL Server service is running on the server.
2. Ensure that you are using the correct server name and instance name.
3. Check if the SQL Server is configured to allow remote connections.
4. Verify if the SQL Server is configured to use TCP/IP protocol.
5. Ensure that the SQL Server Browser service is running.
6. Check if the Windows Firewall is blocking the connection to the SQL Server.
7. Check if any antivirus software or security software is blocking the connection.
8. Check if there are any network connectivity issues.

If you have tried all of the above steps and still unable to connect, you can try the following:

1. Use the IP address of the server instead of the server name.
2. Try connecting using SQL Server Authentication instead of Windows Authentication.
3. Try reinstalling SSMS 19.0.2 or applying any available updates.

Can you show us the full error message?

As there is no difference between SSMS 18 and SSMS 19 in this regard, it boils down to one of two things:

1. You are not spelling the server/instance name correctly.
2. You need to set some connection option for the connection to work. Go to the Options tab in SSMS 18 and SSMS 19 to compare your settings.

Hi @Tahmid Bari

According to official documentation: https://video2.skills-academy.com/en-us/sql/ssms/download-sql-server-management-studio-ssms?view=sql-server-ver16#supported-sql-offerings, version 19.0.2 of SSMS is available for SQL Server 2014 and later, and provides the most important support for working with the latest cloud features in Azure SQL Database and Azure Synapse Analytics.

Please check the suggestions above to troubleshoot the error of not connecting, or provide us with more detailed error information so that we can solve the problem for you.

Best regards,
