Django发送Gmail验证邮件时出现WinError 10060连接超时问题

错误日志

运行Daphne服务器调用send_mail()发送邮箱验证邮件时触发500错误，核心为连接超时：

PS> daphne -p 8000 Server.asgi:application

已排查内容

网络连接：使用Test-NetConnection测试smtp.gmail.com 587端口成功，输出如下：

Test-NetConnection -ComputerName smtp.gmail.com -Port 587
ComputerName     : smtp.gmail.com
RemoteAddress    : --------------
RemotePort       : 587
InterfaceAlias   : Wi-Fi
SourceAddress    : --------------
TcpTestSucceeded : True

排除路由器问题：其他电脑可正常解析smtp.gmail.com
关闭防火墙后问题仍存在
