aws 克隆的 ec2 只显示 nginx 默认页面为什么？

Question

我有一个正在运行的实例，可以在 AWS 上正确显示该网站。运行该网站所需的内容django, nginx, uwsgi包括elastic ip

我已经创建了实例的映像。启动该实例，现在我有了第二个实例，它与第一个实例相同。

第二个实例只是正常floating ip。当我将 IP 输入浏览器时，我希望也能看到我的网站，但由于我尚未进行任何配置，因此只需长时间加载即可，直到超时site-available。

无论如何，我当时只能看到nginx欢迎页面。我转到site-available，将 ip 输入server_name，还设置了dns为subdomain名称。更改后，我重新启动了 uwsgi。

我尝试在浏览器上使用ip，subdomain但仍然显示nginx欢迎页面。甚至没有错误。

有人知道为什么或者建议我该尝试什么吗？

都是相同的设置，不是应该可以正常工作吗？

PS 然后我尝试将其elastic ip从第一个实例移动到第二个实例...我在浏览器中使用了第一个实例的域...然后弹出我的网站而不是nginx欢迎页面

site-available对于原始实例，它运行完美

    if ($scheme != "https") {

}

至于第二个实例...我改变了server_name，并尝试包括和排除，ssl但结果相同

这是第二个实例的配置
