Hello,
We are encountering an issue when trying to enable AI Code Fix with a self-hosted provider (Azure OpenAI) in our SonarQube Server instance.
We have verified connectivity with api.sonarqube.io. The tests confirm:
-
DNS resolution works correctly
-
TCP connection is successful
Despite this connectivity, the feature cannot be activated. The UI displays the following error:
Fail to save settings. Request failed with status code 400
In addition, the web.log file shows the following messages:
2026.03.16 12:17:51 WARN web[4a4b6bcb-2ff8-441e-a648-bc3577f7d240][o.s.w.s.PageNotFound] No mapping for GET /api/v2/fix-suggestions
