So you setting X-FORWARDER_PROTO header to 'https' for non-https 
connection. Probably this is the reason why your app uses https:// 
in redirect.

Hint: if you want to preserve this lines identical between http 
and https servers (e.g. for using identical include file or just 
describing them at http{} level instead of doing so in location{}), you 
may try using $scheme variable. I.e.:

-    proxy_set_header  X-FORWARDED_PROTO https;
+    proxy_set_header  X-FORWARDED_PROTO $scheme;
