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.
