After converting an OpenShift cluster to use BYO / External Authentication, the native OpenShift OAuth server and its related OAuth endpoints are no longer present.

When Loki (via the OpenShift Loki Operator) attempts to auto-discover OpenShift OAuth endpoints, it encounters errors because those endpoints no longer exist in an external-authenticated environment.

This results in repeated errors such as:

level=error name=lokistack-gateway ts=2025-11-08T00:42:05.931886411Z caller=openshift.go:149 tenant=network msg="unable to auto discover OpenShift OAuth endpoints: got 404 404 page not found"

Expected Result

• Loki should support external identity providers without requiring OpenShift OAuth.

• OAuth autodiscovery should be disabled or handled gracefully in external-auth environments.

• No repeated error logs should occur when OAuth is intentionally absent.
