购买的阿里云证书在部署ngix服务器时测试报错

/usr/local/nginx/sbin/nginx -t
nginx: [warn] invalid value "TLSv1.1" in /usr/local/nginx/conf/nginx.conf:179
nginx: configuration file /usr/local/nginx/conf/nginx.conf test failed

下面是我的配置信息

server {
    listen 443;
    server_name localhost;
    ssl on;
    root html;
    index index.html index.htm;
    ssl_certificate   cert/214925189940589.pem;
    ssl_certificate_key  cert/214925189940589.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;
    location / {
        root html;
        index index.html index.htm;
    }
}

ngix:

nginx version: nginx/1.1.10
