Error to connect Datamart SQL Endpoint

Hi Anonymous 

The error "The target principal name is incorrect. Cannot generate SSPI context" is typically related to Kerberos authentication issues within a Windows environment. This error can occur when attempting to establish a connection to a SQL Server using Integrated Security. Here are a few steps to help address this issue:

Ensure that the SQL Endpoint for your Datamart is active and properly configured. Sometimes, connection issues can arise if the endpoint is in the process of refreshing or if there are any ongoing maintenance tasks.

Connection errors can also occur if there are network restrictions in place. Ensure that TCP port 1433 is open, as it is the standard port used for SQL Server connections. This is crucial for both on-premises and cloud environments.
Double-check the authentication method you're using and ensure that your user account has the necessary permissions to access the Datamart. For Datamarts in Power BI, using Microsoft Entra ID (formerly Azure Active Directory) authentication is a common requirement.
On the client side, if you're using a connection string to connect to the SQL Server, ensure that it's correctly formatted and includes the necessary authentication parameters. For Integrated Security, the connection string should include Integrated Security=SSPI.
