If your nginx config is correct, then it might be that the upstream
/ backend service (the flask app, in this case) does not like being
reverse-proxied (to a different "sub-directory"),

Does https://pypi.org/project/flask-reverse-proxy-fix/ apply in your case?

That page links to a 404 page, where the original content appears to be at
https://web.archive.org/web/20131129080707/http://flask.pocoo.org/snippets/35/

You can possibly / potentially avoid all of that, if you are happy
to deploy your app at http://127.0.0.1:8000/app/ instead of at
http://127.0.0.1:8000/ -- in that case, all of the "local" links will
be the same in both the direct and reverse-proxied cases, so only the
hostname/port would need adjusting. (Which is usually more straightforward.)

(I'm presuming that it is possible to deploy a flask app somewhere other
than the root of the web service.)

Good luck with it,
