无法从 Elastic Beanstalk 的 EC2 实例访问外部 MongoDB Atlas 数据库

我拥有一个Elastic Beanstalk 环境，其中包含一个运行Spring Boot 服务器的单个 EC2 实例。我认为没有必要讨论部署选项，但如果需要，我会将它们添加为编辑。

最近，我部署了一个连接到我的MongoDB数据库的代码（使用通过 MongoDB Atlas 托管的外部源），该代码在本地运行良好。当我尝试访问某个页面时，我的 Spring Boot 应用程序当前会列出该数据库中的项目。

在远程，它运行良好，直到我到达尝试查询我的数据库的某个页面。尝试查看 Beanstalk 的web.stdout.log文件时，我收到一些异常：

通过猜测，我认为这样的异常是由于访问数据库 URL（在文件内部正确application.properties定义）时出现问题而引起的。

EC2 安全组允许每个地址到每个端口的出站流量。

我正在使用默认 VPC，没有创建自定义 VPC，并且它的出站规则似乎既允许又拒绝网络流量：

我无法删除明确否认一切的规则。

我是否应该使用自定义 ACL 和自定义出站规则创建自定义 VPC？仅用于访问外部资源（如 MongoDB 数据库）？我可能错过了什么吗？我是 AWS 新手（实践中），刚刚意识到获得 AWS 认证并不能保证你拥有任何实践技能。
