nginx - NGinx SSL 重定向循环

Question

这是我的 nginx 配置文件：

server {
    listen       80;
    server_name  domain.com;
    return 301 https://$host$request_uri;
}
server {
    listen       443;
    server_name  domain.com;
    client_max_body_size 20M;

    ssl_certificate           /path/cert.crt;
    ssl_certificate_key       /path/cert.key;

    ssl on;
    ssl_session_cache  builtin:1000  shared:SSL:10m;
    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers HIGH:!aNULL:!eNULL:!EXPORT:!CAMELLIA:!DES:!MD5:!PSK:!RC4;
    ssl_prefer_server_ciphers on;

    location / {
     proxy_pass http://localhost:9000/;

     proxy_set_header        X-Forwarded-Proto $scheme;
     proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header  Host $http_host;
     proxy_set_header  X-Url-Scheme $scheme;
     proxy_redirect    off;
     proxy_max_temp_file_size 0;

    }

    # Pagespeed
    location ~ "\.pagespeed\.([a-z]\.)?[a-z]{2}\.[^.]{10}\.[^.]+" { add_header "" ""; }
    location ~ "^/ngx_pagespeed_static/" { }
    location ~ "^/ngx_pagespeed_beacon$" { }
    location /ngx_pagespeed_statistics { allow 127.0.0.1; deny all; }
    location /ngx_pagespeed_message { allow 127.0.0.1; deny all; }
}

不幸的是，我得到了一个重定向循环。你能告诉我任何更正吗？
