Question

我只用一个URL就遇到了一个问题，该URL提供了被同伴拒绝的连接。我在服务器中部署了一个Django项目。以前它可以正常工作，但现在却给了我这个错误，在网页上，它显示为空白屏幕。我从视图发送了正确的响应并能够以文本形式显示，但是它没有使用Django模板特殊功能进行渲染。我尝试了许多在堆栈溢出和许多其他网站上可用的方法，但是什么也没有用。我也尝试重新安装Django，并尝试更改URL并重新启动服务器很多次，但是没有用。我使用的是Amazon-ec2 centos服务器，Django版本2.1，python版本是3.7.3。

ConnectionResetError：[Errno 104]由Django和Postgresql中的对等方重置连接
