IPhone / iPad 不会加载 AWL ELB 后面的网站或子域托管
IPhone / iPad will not load website or subdomain hosting behind a AWL ELB
我 运行 遇到了一个难题，即在 AWS 上的 ELB 后面的 EC2 实例上托管的网站无法加载到任何移动 I 设备上。该站点在桌面上的所有浏览器上加载正常。
我的 EC2 是 运行 Centos 和 Apache。
没有错误消息，Safari 只是显示一个空白页面，地址栏会被清除。 Chrome 显示消息 "ERR_FAILED"。
我被这个问题困扰了好几天，在网上找不到太多所以我想分享我的解决方案。
我发现 运行
curl "https://example.com"
返回
HTTP/2 stream 0 was not closed cleanly: PROTOCOL_ERROR (err 1)
经过更多研究，我发现
Application Load Balancers provide native support for HTTP/2 with
HTTPS listeners. You can send up to 128 requests in parallel using one
HTTP/2 connection. The load balancer converts these to individual
HTTP/1.1 requests and distributes them across the healthy targets in
the target group. Because HTTP/2 uses front-end connections more
efficiently, you might notice fewer connections between clients and
the load balancer. You can’t use the server-push feature of HTTP/2. [source]
解决方法：编辑http.conf禁用HTTP/2
改变
Protocols h2 h2c http/1.1
到
Protocols http/1.1
