Reverse proxy problem with an application

[B.R.]

This clearly looks like an application problem and not a nginx-related one.
nginx does not remove cookies nor, as the configuration snippet you shared
suggest, handles authentication.

If you use DNS, make sure all requests are served by the instance of nginx
you quote, including redirects which might happen on login (have a look at
access logs).
You can also investigate the content of cookies received either from
downstream or upstream if you think it is related to your problem.

If you got a question on the nginx configuration this ML is here to help.
Otherwise, you'll need to rereoute your question where appropriate.
