问题描述

我和我的一些同事收到了 net::ERR_SPDY_PROTOCOL_ERROR 错误.

I and a few of my colleagues got the net::ERR_SPDY_PROTOCOL_ERROR error.

我们使用 ngnix 1.8.0 版.错误不稳定(难以复制)，Ngnix错误日志也没有这个错误.

推荐答案

我在尝试为 Chrome 上的 ERR_SPDY_PROTOCOL_ERROR 所面临的问题寻求帮助时遇到了这个问题.认为这可能会使其他人受益.

I came across this question when trying to find help for the problem I was facing with ERR_SPDY_PROTOCOL_ERROR on Chrome. Thought this might benefit others.

我们的情况/解决方案:我们使用连接到 EC2 实例的 AWS Application Load Balancer.我们在 EC2 代理上运行的脚本之一是来自客户端浏览器的请求.我们最近更新了脚本 - 没有相关更改 - 并注意到 Chrome 和 Safari 对代理脚本的请求开始失败.Chrome 显示了 ERR_SPDY_PROTOCOL_ERROR 错误，当我们深入研究时，我们可以看到此请求使用的是 HTTP/2.Firefox 请求继续正常工作.

Our situation / solution: We use an AWS Application Load Balancer connected to EC2 instances. One of the scripts we run on EC2 proxies requests from the client browser. We recently updated the script - no relevant changes - and noticed that both Chrome and Safari requests to the proxy script started failing. Chrome showed the ERR_SPDY_PROTOCOL_ERROR error and, when we dug in to it, we could see this request was using HTTP/2. Firefox requests continued to work fine.

我们的解决方案:我们关闭了 ALB 中的 HTTP/2 支持.立即解决了问题.

Our solution: we switched off HTTP/2 support in the ALB. Immediately solved the problem.

AWS CLI 命令:

AWS CLI command:

aws elbv2 modify-load-balancer-attributes --load-balancer-arn <your_load_balancer_arn> --attributes Key=routing.http2.enabled,Value=false
