我一周前在Digitalocean上建立了一个使用django和postgres制作的网站，然后按照django nginx，gunicorn和postgres教程here进行了操作，并使用了数字空间作为我们的静态文件。当我们在生产环境中测试网站时，整个一周的一切运行都很好，一切正常（出于测试原因，将Debug = true保留）。几小时前，在我测试了一些东西之后突然出现了502错误的网关错误。我检查了nginx错误日志，并在此显示错误：
2019/12/23 00:30:00 [错误] 7988＃7988：* 2202 recv（）失败（104：对等重置连接），同时从上游读取响应头，客户端：125.0.0.1，服务器：www .myapp.com，请求：“ GET / reviews / business / id = 3 / HTTP / 1.1”，上游：“ http://unix:/run/gunicorn.sock:/reviews/business/id=3/”，主机：“ myapp.com”，引荐来源网址：“ https://myapp.com/category/Salon/” 2019/12/23 00:30:12 [错误] 7988＃7988：* 2208 connect（）到Unix：/run/gunicorn.sock在连接到上游时失败（111：连接被拒绝），客户端：125.0.0.1，服务器：www.myapp.com，请求：“ GET / reviews / business / id = 3 / HTTP / 1.1”，上游：“ http://unix:/run/gunicorn.sock:/reviews/business/id=3/”，主持人：“ myapp.com”，引荐来源网址：“ {{3} }” 2019/12/23 00:30:25 [错误] 7988＃7988：* 2212到unix的connect（）：/ run / gunicorn.sock在连接到上游时失败（111：连接被拒绝），客户端：125.0.0.1，服务器：www.myapp.com，请求：“ GET / HTTP / 1.1”，上游：“ https://plentypot.biz/category/Salon/”，托管：“ myapp.com”
我运行了nginx -t并成功返回，表示配置一切正常
使用命令journalctl -u gunicorn记录gunicorn错误，其输出为：
