"Internal error SqlLoginFailureException"

amolt — Wed, 27 Aug 2025 14:03:10 GMT

Hello,
For some time now, I have been receiving an error message at a certain Lakehouse endpoint:
“Internal error SqlLoginFailureException”
I noticed that the metadata between the lake and the endpoint was not up to date in the endpoint.
I couldn't find any other solution than to delete the lake and recreate it. I tried several times to update this metadata, without success.
As I don't have a support contract with Microsoft, I wasn't able to open a ticket.
Have you ever had this problem and do you have a solution to fix it?

Thank you for your help.
