Why Do 502 Errors Appear Only on POST Requests After Migrating to PaaS?

After moving an application to a PaaS platform, intermittent 502 errors occur, seemingly only for POST requests, but the root cause lies in Nginx‑Ingress and uwsgi HTTP version mismatches, connection reuse, and retry behavior, which can be diagnosed through traffic analysis and configuration changes.
