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).
