Here nginx returned 400 (Bad Request).  Since number of bytes sent 
to client logged as 0 it's looks like connection has been dropped 
by client while sending request.  It shouldn't involve any 
upstream work after error was detected though.

Some detailed info should be logged at info level.  If your config 
hasn't changed from initial post - your logging level currently 
set to error which isn't enough to see such messages.

Could you please try to obtain debug log for such request?
