Most often this question is asked when gzip is enabled on a
backend host, and hence nginx sess gzipped content which it can't
change. Where you tried to disable gzip? Correct thing to do is
to disable gzip on a backend. Alternatively, you may do

proxy_set_header Accept-Encoding "";

on nginx side. This will inform backend that content encodings
aren't acceptable and will effectively disable gzip on a backend
as well.
