Question

我们使用Twilio Video开发我们的系统，我可以将系统与我自己的笔记本电脑一起使用，但是在尝试连接Chrome浏览器时工作的笔记本电脑出错了。

我收到以下错误：

WebSocket connection to 'wss://endpoint.twilio.com/' failed: Error during WebSocket handshake: 'Upgrade' header is missing

完整错误文本如下：

我们甚至不了解实际上是什么问题。

Answer 1

此错误消息表示您尝试连接到HTTP服务器而不是WebSocket服务器。

可能的原因：

您使用的URI不正确（过去我见过这种格式的正确twilio websocket URI：wss：//xxx.endpoint.twilio.com。在您的示例中缺少xxx部分）
您支持某些不支持WebSocket的HTTP代理

连接到端点时WebSocket握手错误
