So you see it's correctly compressed, but some external website
checkers report it's not. Most likely it's caused by using
HTTP/1.0 checks on these checkers. You may try to set

gzip_http_version 1.0;

to make these checkers happy. But I would recommend to keep the
default (gzip_http_version 1.1) instead to avoid problems with
real HTTP/1.0 clients/proxies.
