Internal error SqlLoginFailureException

[amolt]

Hello, 

I can no longer use the SQL endpoint of some Lakehouses.
I've tried refreshing the metadata, but I consistently get the error message “Internal error SqlLoginFailureException”

does anyone have any ideas?

Hi @amolt ,

Thank you for reaching out to Microsoft Fabric Community Forum.

can you try the below debug to steps to solve your issue.

• Ensure you have the correct permissions on the Lakehouse (e.g., Lakehouse Contributor or higher).

• Check if the SQL analytics endpoint is enabled in the Lakehouse settings.

• Sign out and back in to refresh your authentication token.

• Clear browser cache if you're using the Fabric portal.

• Verify that the Lakehouse or workspace hasn’t been renamed or moved.

• Make sure you're using the latest SQL endpoint URL.

• Try connecting using a different tool (e.g., SSMS, Azure Data Studio, Power BI Desktop).

• Check the Microsoft Fabric status page for any ongoing issues.

• Review the Power BI Support Portal for related incidents.

• Raise a Microsoft support ticket if the issue persists.

Hi @amolt ,

Can you check who is the owner of the Lakehouse?. This issue may occur if the owner of the lakehouse's credential expired

Hi @amolt ,

How you are refreshing the metadata. Are you using api?

@Srisakthi ,

No, I use the refresh button in the portal.

@Srisakthi ,

I've had this problem with other lakehouses, but refresh of the metadata solved the problem.
In this case, I get the error message during the metadata refresh.

hi @Srisakthi,

Thanks for your reply.
I'm the lakehouse owner and I don't have the problem on all lakehouses.
