我在我的NGINX服务器上有HTTP2协议的问题，这是我的configuration
listen 443 ssl http2; server_name adomain.com; root /var/www/project; limit_req zone=one burst=60 nodelay; add_header Strict-Transport-Security "max-age=2592000; includeSubdomains;" always; ssl_certificate /etc/letsencrypt/live/fullchain.pem; ssl_certificate_key /etc/letsencrypt/live/privkey.pem; ssl_protocols TLSv1 TLSv1.1 TLSv1.2; ssl_ciphers "EECDH+AESGCM:EDH+AESGCM:ECDHE-RSA-AES128-GCM-SHA256:AES256+EECDH:DHE-RSA-AES128-GCM-SHA256:AES256+EDH:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384:ECDHE-RSA-AES256-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-RSA-AES256-SHA:ECDHE-RSA-AES128-SHA:DHE-RSA-AES256-SHA256:DHE-RSA-AES128-SHA256:DHE-RSA-AES256-SHA:DHE-RSA-AES128-SHA:ECDHE-RSA-DES-CBC3-SHA:EDH-RSA-DES-CBC3-SHA:AES256-GCM-SHA384:AES128-GCM-SHA256:AES256-SHA256:AES128-SHA256:AES256-SHA:AES128-SHA:DES-CBC3-SHA:HIGH:!aNULL:!eNULL:!EXPORT:!DES:!MD5:!PSK:!RC4"; ssl_prefer_server_ciphers on; ssl_session_cache shared:SSL:10m; ssl_session_timeout 10m; ssl_dhparam /etc/nginx/ssl/dhparam.pem; resolver 8.8.8.8; ssl_stapling on; ssl_stapling_verify on; keepalive_timeout 70; 我看不到我的iOS设备上的错误（safari 11），很奇怪，网页是一个SPA（angular度），应用程序向API发出请求，应用程序通过HTTP2加载，但是当应用程序必须向API失败，从listen禁用HTTP2会使所有事情都按照预期工作
两个服务器前端/后端的密码是相同的
在Chrome / Firefox / IE工作正常，我不知道Safari或我的服务器configuration有什么问题
当Safari失败时，error.log和adomain-error.log是空的

UPDATE
我的iPhone上的控制台说Protocol error所以我很确定这是IOS 11的错误
更新2
我find了这个post

它解释说，如果你支持TLSv <1.2，你最终会出现一个PROTOCOL ERROR ，在我的服务器configuration中只剩下TLSv1.2让应用程序再次运行，但是它有问题，有些请求会失败……这超出了我的理解，一次再次在Chrome / Firefox的工作，但在我的移动Safari浏览器不
