Further investigation into the OAuth2 redirect issue in Power BI Service suggests the problem may be related to the authentication browser mechanism, specifically the WebView2 Runtime used by Power BI.
- In Power BI Desktop, enabling the “Use my default web browser” option reproduces the same blank redirect issue seen in the Service.
- Power BI Service does not allow switching the authentication browser and relies on WebView2 Runtime internally.
- WebView2 is responsible for rendering embedded authentication dialogs, including OAuth2 flows.
- The redirect page appears blank and visually different from usual, indicating a possible issue with how the embedded browser is handling the authentication flow.
We are getting the same issue here, attempting to use OAUTH2 to authenticate a connection to an on-prem gateway. The redirect browser window appears blank, we have tried multiple different browsers (Edge, Chrome, Firefox) so your point about the WebView2 runtime sounds correct.
