原文 2019-09-06 16:52:26 3 1 azure/ signalr

I am getting an error in my application whereby the connection over wss:// is failing. 我的应用程序中出现错误，因此通过wss：//的连接失败。

The browser gets a 200 status code, and I see the log line in ASP.NET Core app that looks like: 浏览器获得200状态代码，我在ASP.NET Core应用中看到如下日志行：

{"@t":"2019-09-06T16:46:58.0850696Z","@m":"Failed connection handshake.","@i":"ebdbcf97","@l":"Error","EventId":{"Id":5,"Name":"HandshakeFailed"},"SourceContext":"Microsoft.AspNetCore.SignalR.HubConnectionContext","TransportConnectionId":"qLt39WTMAY4t-Q4vyRTGrg","RequestId":"0HLPISG9A2QAE:00000006","RequestPath":"/hubs/results","CorrelationId":null,"ConnectionId":"0HLPISG9A2QAE"} {“ @t”：“ 2019-09-06T16：46：58.0850696Z”，“ @ m”：“连接握手失败。”，“ @ i”：“ ebdbcf97”，“ @ l”：“错误”，“ EventId“：{” Id“：5，” Name“：” HandshakeFailed“}，” SourceContext“：” Microsoft.AspNetCore.SignalR.HubConnectionContext“，” TransportConnectionId“：” qLt39WTMAY4t-Q4vyRTGrg“，” RequestId“：” 0HLPISG9A2QAE： 00000006“，” RequestPath“：” /集线器/结果“，” CorrelationId“：null，” ConnectionId“：” 0HLPISG9A2QAE“}

Browser error: 浏览器错误：

WebSocket connection to 'wss://frontend.env.company.com/hubs/results?id=qLt39WTMAY4t-Q4vyRTGrg' failed: Error during WebSocket handshake: Unexpected response code: 200 WebSocket与'wss：//frontend.env.company.com/hubs/results？id = qLt39WTMAY4t-Q4vyRTGrg'的连接失败：WebSocket握手期间出错：意外的响应代码：200

The application is running behind an nginx in a kubernetes cluster hosted on Azure. 该应用程序在Azure托管的kubernetes群集中的nginx后面运行。 It's fronted by Azure CDN which routes certain /paths to this origin/endpoint. 它以Azure CDN开头，它将某些/ path路由到此起点/端点。

Any help would be appreciated. 任何帮助，将不胜感激。

Thanks! 谢谢！

The explanation is that Azure CDN with Premium Verizon does not support WebSockets. 原因是带有Premium Verizon的Azure CDN不支持WebSockets。 Have moved away from that as a solution and used nginx instead, which works beautifully. 已经不再使用它作为解决方案，而是使用了nginx，效果很好。
