java - io.netty.handler.codec.http2.Http2Exception:意外的HTTP/1.x请求:GET/

我想测试Zeebe（camunda版本），然后按照以下documentation中所述的步骤进行操作。简而言之，我基于命令docker run --name zeebe -p 26500:26500 camunda/zeebe:latest将Zeebe作为docker容器运行。

查看初始日志，似乎一切正常。但是，当我尝试使用Chrome访问代理时，我会在日志中看到以下错误：

我使用zbctl检查了Zeebe状态（zbctl状态-不安全），它看起来很健康：

Cluster size: 1
Partitions count: 1
Replication factor: 1
Gateway version: 0.23.0-alpha2
Brokers:
  Broker 0 - 172.17.0.2:26501
    Version: 0.23.0-alpha2
    Partition 1 : Leader

有人看过这个问题吗？

最佳答案

显然，浏览器正在发送简单的旧http / 1.x请求。
尝试使用更灵活的东西，例如curl：

curl -I -k --http2 https://yourhost
