AWS Appsync 订阅 - “连接失败：连接握手错误”

Question

我正在尝试在 AWS amplify 的 appsync 上运行一个简单的订阅。

订阅永远不会触发，大约 30 秒后，我在 appsync 控制台中等待子时收到此错误消息：

Error: {
    "errors": [
        {
            "message": "Connection failed: Connection handshake error"
        }
    ]
}

如果我从浏览器重新创建调用，我会收到此错误：

Answer 1

我找到的唯一解决方案是更换我的路由器......

不知道为什么会有所不同，尝试了我能想到的所有路由器设置

我使用我的家庭 LTE WiFi 路由器并不断收到此错误，最终从我的手机提供商那里更改为基于 sim 卡的本地路由器，并且每次都连接。

我已经在许多不同的模型上使用了它，并且每次都可以使用。 出现故障的路由器是华为B525路由器，其他任何路由器都没有问题...
