django，找不到静态文件404

Question

nginx中的静态文件出现错误

INSERT INTO [dbo].[Time] 
    SELECT DENSE_RANK() OVER (ORDER BY [YEAR], [MONTH]) , [YEAR] , [MONTH] 
    FROM (SELECT DISTINCT [YEAR], [MONTH] 
        FROM [dbo].[yearclass]
    ) yearmonthclass;

这是我的Nginx配置：

custom_main.css:1 Failed to load resource: the server responded with a status of 404 (Not Found)

我该怎么办？
