[error] [default] Error sending telemetry FetchError: The pending stream has been canceled (caused by: unable to verify the first certificate)

我在VS Code使用Github Copilot时遇到了一个问题。报错信息如下:

[error] [default] Error sending telemetry FetchError: The pending stream has been canceled (caused by: unable to verify the first certificate)

具体信息：

2024-07-23 17:44:56.712 [error] [default] Error sending telemetry FetchError: The pending stream has been canceled (caused by: unable to verify the first certificate)

  code: 'ERR_HTTP2_STREAM_CANCEL',
  errno: undefined,

}

而我最近一直可以正常使用Github Copilot，为什么会出现这个错误呢?

经过仔细琢磨，我找到了原因。

我安装了一个工具FastGithub，它可以帮助我们以稳定和快速的方式访问Github官网。当它工作时，有可能会影响或改变Github的DNS或代理(proxy)，从而导致Github Copilot无法验证证书(certificate)。

我们改变服务 fastgithub 和FastGithub.dnscrpyt.proxy的启动类型为 手动，然后手动停止fastgithub服务。

这之后，发现Github Copilot可以正常工作了。

Tip

如果想要继续使用fastgithub服务，手动启动 它即可，不过这会导致上述问题复现， 即目前二者不能同时工作。
