Unfortunately nginx site lacks sane examples.

If you happen to have Host: header based virtual servers on the same
backend and you don't use separate nginx server {} sections for those
virtuals on the frontend, you want to use $host variable within
proxy_cache_key.

I use
proxy_cache_key $scheme://$host$request_uri;

This may be the side effect of the application on the backend,
which behaves this way when it cannot set cookies ( doesn't receive
it after trying to set it ). Use
proxy_pass_header Set-Cookie;
within your proxying location / {}
