<!-- Answer -->
Your config and proxy setup are correct, but Superset 6.0.0 has known, unresolved bugs with subpath deployments—especially double prefixing and 404s after login or navigation. These issues are fixed only in releases after late 2025 (see [PR #35098](https://github.com/apache/superset/pull/35098) and related discussions). The API works because backend routing is less affected, but the UI and static assets break due to these bugs.
If you can, upgrade to a Superset version that includes or is newer than PR #35098. If upgrading isn’t possible, you’ll keep hitting these 404s and double-prefix issues—there’s no robust workaround in 6.0.0. For now, double-check that your Istio rewrite and headers are consistent, and that you’re not setting both the prefix in the path and in headers at the same time. If you must stay on 6.0.0, consider using a subdomain instead of a subpath, or apply a targeted patch from the PR above.
Let me know if you want a checklist for subpath deployment or help reviewing your exact Istio YAML for any subtle issues.
