Layers from Enterprise stopped loading in the published Power BI Report. (Local Network Access)

Question

ArcGIS layers (retrieved from internal Enterprise portal) on their Power BI report stopped loading recently. It used to work well before. Looking at the network traffic, it gives CORS error.

We confirmed all Power BI domains are added to the 'Allow origins' settings at the portal security level.

This seems to be related to the new security feature called 'Local Network Access' recently added to Chrome and Edge. Disabling this security settings solve the issue. However, we do not recommend this approach, as it reduces the security posture of modern web browsers! Should this be logged as a defect and have Esri’s developers determine whether it can be addressed within the product code or is it ultimately a browser‑related issue?

Hi @MohamadChibli and @TanjaHH,

Thank you for letting us know! We will keep you updated.

@MohamadChibli , could you please confirm whether you’re seeing this issue with the local network setting enabled or disabled? From your message, it seems like it’s enabled, but I just want to confirm. On my end, when the local network setting is enabled, the layer loads correctly.

Thank you!

Thanks for your post!! I also had the issue and couldn't figure out the problem. Now I just had to allow the access for app.powerbi.com in the browser settings in Edge and it worked instantly  🙂

For some reason I was the only one in my team with this issue, although the others also work in Edge. So I'm not sure if this issue needs to be solved within the product code. On the other hand, as a report builder not too familiar with security features etc and due to it being only a problem for me, it was a really baffling problem. If you hadn't posted this, it probably would have taken me ages to solve it.
