Issue resolved.

Summary:

Root cause: Domain port was 8001, app was on 8080
Why it kept reverting: Tool-based changes weren't sticking; manual UI change worked
Solution: Changed port to 8080 manually in Railway dashboard, redeployed
Status: Working

You can cancel the Railway support ticket if you want. The issue is fixed.

Glad you got it sorted! The domain target port mismatch was indeed the issue. Thanks for sharing the resolution.
