求助 nginx 开启 http2

证书是 letsencrypt 配置如下

server {

    #listen   80;
    listen   443 ssl http2;
    server_name areyoufuckingme.com;

	ssl_certificate /etc/letsencrypt/live/areyoufuckingme.com/fullchain.pem;
	ssl_certificate_key /etc/letsencrypt/live/areyoufuckingme.com/privkey.pem;
	ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:AES256+EECDH:AES256+EDH";
	ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
	ssl_prefer_server_ciphers on;
	ssl_session_cache shared:SSL:10m;
    index index.php index.html index.htm;
    set $root_path '/Data/areyoufuckingme/public';
    root $root_path;

    location / {
        try_files $uri $uri/ /index.php?_url=$uri&$args;
    }

    location ~ \.php$ {
            try_files $uri =404;
            fastcgi_split_path_info ^(.+\.php)(/.+)$;
            fastcgi_pass unix:/tmp/php-cgi.sock;
            fastcgi_index index.php;
            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
            include fastcgi_params;
    }
    location /.well-known {
        allow all;
    }

}

Nginx开启了h2模块

nginx version: nginx/1.10.0
built by gcc 4.4.7 20120313 (Red Hat 4.4.7-17) (GCC) 
built with OpenSSL 1.0.1e-fips 11 Feb 2013
TLS SNI support enabled
configure arguments: --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-http_v2_module --with-http_gzip_static_module --with-ipv6 --with-http_sub_module --with-ld-opt='-ljemalloc'

目前的问题是 ssl 生效了 但是 http2 没生效。。

好奇怪 只有一个css和js开始H2 剩下的不是h1就是spdy...
