Hi Dionah,

A 404 from Power BI Desktop usually means Desktop is trying to reach a Lakehouse URL or SQL endpoint that doesn’t exist for your account, or isn’t exposed the way you’re connecting. The most common causes are using the wrong connector, an outdated Desktop build, or missing permissions on the Lakehouse’s semantic model or SQL endpoint.

How are you tryung to connect, over SQL Endpoint or directly through OneLake?

What verison of PowerBI Desktop are you using?

Hi Dionah,

Can you try updating to Aguust 2025 version of PowerBI Desttop and try again? Your version is quite old.

Hi Dionah

I have built a lakhouse which contains just two tables from dataverse from dataflow Df (Cf. Image 1).

When I try to connect it in my Power BI Desktop, I got an error 404, (cf image 2). Why do you need a Power BI Desktop. Microsoft has moved into the cloud database using Fabric SQL/ Lakehouse. Also, Could you please send the screenshot of Power Query online??
