404 Not Found nginx - 提交表格

Question

我在laravel项目中工作，我的表单是用ajax提交的， 目标是使用数据用户输入创建具有“intervation图像”的图像。

实际上，如果我的代码要创建30个图像需要大约20/40秒，但如果我想要创建100个或更多图像，它会停止并返回错误：

404 Not Found

nginx/1.10.0 (Ubuntu)

我认为这是由于php的时间限制，所以我增加了限制：

资源限制

max_execution_time = 120
max_input_time = 120
memory_limit = 128M

但它返回相同的错误，我可以附加一些控制台的截图
