The configuration as shown is clearly invalid. Anyway, there are
some things you may want to try:

- Try looking into error log. In most cases, it contains details
on what goes wrong.

- Try to enable debug logging, see
http://nginx.org/en/docs/debugging_log.html. It contains
details on all operations done by nginx, and can be used to
debug varios problems.

- Make sure your backend properly works via HTTP/1.0 and/or try
using "proxy_http_version 1.1" (if your backend is expected to
return chunked responses, it might be confused by HTTP/1.0).
