我无法从Parse Dashboard上传PFFile（图像），当我的解析服务器使用https尝试在浏览器中访问它时，我得到404

我在数字海洋上使用nginx代理方法使用https解析服务器。我的解析服务器网址类似于https://my-domain.com/myappname。我已将此索引添加到index.js文件中我的解析服务器的publicServerURL上，以用于mailgun和文件。

我还在Parse Dashboard的config.json文件中将此链接作为serverURL添加了。我试图通过Parse Dashboard上传pffile（图像），但显示无法连接到Parse API。当我将config.json文件中的serverURL从https://my-domain.com/myappname更改为http：// server-ip：port / parse时，它可以正常工作，但尝试时出现错误从数据库中删除一行（使用https，此功能可以正常工作）

以下是我在/etc/nginx/sites-enabled/my-domain.com中的文件（我还将网站与解析服务器托管在同一服务器中）：

我也无法通过网络浏览器访问上传的PFFile（image）。网址https://my-domain.com/myappname/files/11d51c92517ace2d17bc376f2da99a50_default.png表示404 Not Found nginx / 1.14.0（Ubuntu）
