我一直在使用 Spring Boot 3.2.5 实现电子邮件发送功能，但我似乎无法解决错误，所以我在这里寻求帮助
代码和电子邮件在其他人的计算机上运行良好，但我是唯一在我的计算机上遇到错误的人
首先，错误代码如下所示。
我使用的是 Windows 11 Pro，端口 587 上是 Gmail，但电子邮件在其他计算机上运行正常
我尝试将端口更改为465，但仍然遇到同样的错误。我还尝试使用不同的网络，关闭安全程序，并确保调整防火墙设置以允许顺利操作，但我仍然面临同样的错误
我需要调整什么才能解决这个问题吗？ 我什至尝试过重新安装Windows....☹️

我在各种人工智能（包括 ChatGPT）的帮助下尝试对我的计算机进行多次修改，但同样的错误仍然存在......拜托，我需要你的帮助。
验证您可以使用 telnet 等其他工具连接到 gmail 服务器。如果连接成功你应该有
$telnet imap.gmail.com 587
