nginx 提供大图像

Question

我的页面上的一些图像在 Safari 中会丢失，控制台Failed to load resource: The network connection was lost. 图像服务器中的消息是不同的域，我可以通过在其他浏览器选项卡中粘贴 URL 正确看到图像。

我找到了这个 https://gist.github.com/voronianski/791ef517c5392d7ce5fb但我不知道如何解决？

更新
我将图像文件夹复制到同一个域下进行测试，但仍然出现相同的错误，我以不同的分辨率存储图像，因此我测试是否选择所有较小的尺寸并可以工作。如何解决这个问题？我错过了什么吗？我应该增加keepalive_timeout什么吗？
我通过将send_timeout2 增加到 60 来解决这个问题，它可以正确获取所有图像。增加 可以吗send_timeout？正确的解决方法是什么？
