In the UK South region, we are experiencing issues with the SQL Server login. Although we are using the correct username and password, the login fails when attempting to call the method ensureCreated from Entity Framework, we encounter the error: “System.Data.SqlClient.SqlException: Login failed for user ‘myUsername’.”

When we attempted to create the database in a different region, the connection was successful and the databases were created. image (7)

Hi @nikithakoshy,

Welcome to the Microsoft Q&A and thank you for posting your questions here.

As I understand, you are encountering a login failure for SQL Server in the UK South region while using Entity Framework's EnsureCreated() method.

Here are some steps you can take to troubleshoot the issue:

Ensure that the SQL Server in the UK South region is set up to allow SQL Server Authentication. If it only allows Windows Authentication, that could be the reason for the login failure.
Confirm that the user myUsername has the necessary permissions on the SQL Server instance. The user should have at least the db_owner role for the database you’re trying to create.
Verify that the firewall settings for your SQL Server allow traffic from the application’s IP address. Ensure that the necessary ports (typically 1433 for SQL Server) are open.
Check the SQL Server error logs for any detailed error messages related to the login failure. This can provide clues as to why the authentication is failing.
Use SQL Server Management Studio (SSMS) or a similar tool to manually connect to the SQL Server instance with the same credentials. If you can log in through SSMS but not through your application, it points to a configuration issue in your application.

Hope this helps. Do let us know if you any further queries.

Hi @Mahesh Kurva
Thanks for your response. We are able to login to the server through Azure Data studio with SQL authentication. The user has db_owner role and the firewall rules are fine
In terms of the application configuration, the same configuration works when executed in a different region.

Hi @Mahesh Kurva , Thanks for your response.

We are able to login to the server using Azure Data studio using SQL Authentication. The user has db_owner permissions and the firewall settings are fine.
The same code works on a different region (say West Europe). This issue that we see is present only in the uksouth region, when using EnsureCreated

Hi @nikithakoshy,

Thanks for getting back to me.

Use SQL Server Management Studio (SSMS) to manually connect to the SQL Server instance with the same credentials. If you can log in through SSMS but not through your application, it points to a configuration issue in your application.

I hope this information helps. Please do let us know if you have any further queries.
