gzip compression is working for html pages, but not for css or js, I've found several similar questions, including the following, and tried the suggested solutions, I've tried various settings for (gzip_buffers, gzip_min_length, gzip_comp_level) but none have worked.
What else could be affecting this, why aren't the js or css files compressed?
NGINX gzip not compressing JavaScript files
nginx gzip compression not working
enable gzip compression with nginx
I have the following http block in nginx conf:
http {
upstream fastcgi_backend {
server 127.0.0.1:9000;
}
sendfile on;
tcp_nopush on;
tcp_nodelay on;
keepalive_timeout 65;
types_hash_max_size 2048;
include /etc/nginx/mime.types;
default_type application/octet-stream;
ssl_protocols TLSv1 TLSv1.1 TLSv1.2; # Dropping SSLv3, ref: POODLE
ssl_prefer_server_ciphers on;
access_log off;
#access_log /var/log/nginx/access.log;
error_log /var/log/nginx/error.log;
# Enable Gzip compression
gzip on;
gzip_vary on;
gzip_buffers 128 4k;

# Don't compress anything under 256 bytes
gzip_min_length 256;

Check the conf.d folder for other conf files that may be overriding nginx.conf, you should see at least one file with a server block for the hostname/IP Nginx is serving. Looks like this:
server {
listen 80;
listen [::]:80;
server_name example.com;
return 301 https://example.com$request_uri;
}
server {
listen 443 ssl http2;
listen [::]:443 ssl http2;
server_name example.com;
...
}
You can always search for the server blocks: $ grep -rl "server_name" /etc/nginx
