我是服务器端进程的初学者，有关该主题的其他问题运行的堆栈与我不同，因此很难找到可用的答案。

我很可能在服务器块中的 IP 地址上犯了一个愚蠢的错误，但由于我是一名初学者，所以这并不明显。

我在 Digital Ocean 上运行 Django 2.1 应用程序，使用Nginx和supervisor。我的应用程序使用Django channels因此daphne我使用supervisor(asgi而不是uwsgi)。

我还在 Let's Encrypt 注册以获取 SSL 证书。

Supervisor 和 Nginx 正在运行，我看到

502 Bad Gateway当我输入我的域名时。

nginx 日志显示

这显然表明另一个程序正在使用port 8000。

然而sudo netstat -nlp | grep 8000什么也没有返回。

如果有人能看一下这个问题我将非常感激，就像我说的，我相信对于这个领域具有更高技能水平的人来说这个问题是显而易见的。

非常感谢。

通过更改为解决了这个问题

command=/home/Env/myapp/bin/daphne -u /run/daphne/daphne%(process_num)d.sock --fd 0 --access-log - --proxy-headers mysite.asgi:application

所以它能够执行daphne命令
