Self-hosted API and Chrome/Edge compatibility

25 November 2025 (Edge affected from 10 December 2025): Following the latest Chrome/Edge update, compatibility issues have been identified affecting use of Chrome or Edge with the Self-Hosted API. The root cause is the implementation of stricter network security policies in Chrome and Edge browsers, which prevent properly calling the Self-Hosted API, due to visuals being rendered in an IFrame.

Impact

• The accoPLANNING visual embedded in Power BI Service fails to communicate with the self-hosted API when accessed via Chrome/Edge.

Root Cause

• New policy in Chrome and Edge browsers enforce enhanced restrictions on requests to private IP addresses, requiring explicit permission, which Power BI does not pass down to their IFrames for visuals. Resulting in blocked API calls

Solutions

We always recommend that all customers verify either approach with their internal security responsibility instance, as IT security should be taken seriously in all environments.
Looking ahead, the recommended long-term solution will be as described below. We will update the documentation to reflect this.

Recommended Solution

For customers using the Self-Hosted API, the recommended approach is clear - host the API on a public IP address or domain.
This is necessary because the network security policy in Chrome and Edge browsers block traffic to private IP addresses. By hosting the API on a public endpoint, you ensure compatibility and avoid disruptions caused by these restrictions.

Alternative Workaround

As a short-term workaround, user can disable this policy for a short period. While it can theoretically reduce browser security, this setting was previously not enabled by default in Chrome and Edge browser and therefore did not pose an issue. This makes it reasonable to use this temporary workaround until the long-term solution is in place.
