远程服务器VS Code中GitHub Copilot突然无法使用问题求助

问题背景 #

远程服务器上的GitHub Copilot突然无法工作，本地VS Code的Copilot可正常使用；已确认服务器能ping通api.github.com，但日志显示请求https://api.github.com/copilot_internal/v2/token超时，且连接140.82.112.21:443失败。

解决方案 #

• 验证TCP 443端口连通性：ping仅验证ICMP可达，需测试HTTPS端口。执行以下命令：

  telnet api.github.com 443
  # 或用curl测试具体请求
  curl -v https://api.github.com/copilot_internal/v2/token
  

  如果无法建立连接，说明服务器出站443端口被限制。

• 检查防火墙/安全组规则：确认远程服务器的防火墙、云服务商安全组允许出站访问api.github.com和copilot-proxy.githubusercontent.com的443端口。

• 重置Copilot认证状态：在远程VS Code中按Ctrl+Shift+P（Mac为Cmd+Shift+P），输入GitHub Copilot: Sign Out，完成后重新登录账号。

• 更新/重装Copilot扩展：在远程VS Code的扩展面板中，更新GitHub Copilot到最新版本；若问题依旧，卸载后重新安装，同时检查/home/xhl/.vscode-server/extensions目录的读写权限是否正常。

• 调整VS Code代理设置：打开远程VS Code的设置（Ctrl+,），搜索http.proxy，若服务器无需代理，清空该设置并将http.proxySupport设为off；若需代理，配置正确的代理地址。

• 测试Copilot专用域名：执行telnet copilot-proxy.githubusercontent.com 443，确认该域名的443端口可连通，部分环境可能仅限制Copilot的专用服务域名。
