In centos7 gzip works

In windows10 wifi:name1, gzip does not work

In windows10 wifi:name2, gzip works

But tomcat 8 gzip works in all places

My nginx config:

user  nginx;
worker_processes  1;

error_log /var/log/nginx/error.log warn;
pid /var/run/nginx.pid;

events {
    worker_connections  1024;

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request"'
                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout 65;

    gzip on;
    gzip_proxied any;

    server {
    listen       80;
    server_name  lrs.sout.fun;
    location / {
        proxy_pass  http://lrs:8060;
        index  index.html index.htm;

    server {
    listen       80;
    server_name  jenkins.sout.fun;
    location / {
        proxy_pass  http://jenkins:8080;
        index  index.html index.htm;

I have disabled the cache. so,is nginx gzip compression work related with network?

How to solve this problem? Why tomcat8 doesn't have this problem?

    Notice the gzipless response doesn't have the Server: header with nginx version while others do; this is the main indicator of your problem. Anyway, gzip compression isn't related to the l2 media, such as cable or radio. – drookie Jan 13 at 16:28

    Something appears to have intercepted your connection. Always use https. – Michael Hampton Jan 13 at 16:39
  • The final reason was that our router was implanted with virus. – liunewshine Jan 28 at 1:45
