我们使用 Twilio Video 来开发我们的系统，我可以在我自己的笔记本电脑上使用该系统，但工作的笔记本电脑在尝试连接 Chrome 浏览器时出现错误。

我收到以下错误：

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

完整的错误文本如下：

我们甚至不明白实际上是什么问题。

此错误消息意味着您正在尝试连接到 HTTP 服务器而不是 WebSocket 服务器。

可能的原因：

  1. 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）
  2. 你在一些不支持 WebSocket 的 HTTP 代理后面
