Datamart Login Fails Power Automate

Hello, im trying to create a power automate flow that query's my datamart.

I can connect into the datamart fine with SSMS and query the tables

However, when i try connect with either SQL or AZ SQL connectors in flow, I get a login failed back from the datamart.

I am using the same AZAD auth in the flows like in the SSMS, but get back this error:

Any idea's on what might be the issue? Or where to start looking?
