如何正确调试sentry并查找502 nginx错误的原因

Question

我是 sentry 和 Nginx 的新手，我很难弄清楚我的实例中发生了什么，以及为什么我从 Nginx 收到 502。

在哪里可以找到问题的根源？我尝试使用 tail -100 /var/log/nginx/error.log 但我看不出问题出在哪里...

来自tail /var/log/nginx/error.log的输出：

2021/04/30 17:08:55 [error] 68825#68825: *7 upstream timed out (110: Connection timed out) while connecting to upstream, client: 172.28.132.95, server: mydomain.com, request: "GET / HTTP/1.1", upstream: "https://myip:9000/", host: "mydomain.com"
2021/04/30 17:09:08 [alert] 68825#68825: *17 open socket #9 left in connection 3
2021/04/30 17:09:08 [alert] 68825#68825: *16 open socket #8 left in connection 4

2021/04/30 17:09:08 [alert] 68825#68825: aborting

我发现的唯一奇怪的事情是 upstream 使用我的实例 IP 地址并且主机被解析为 mydomain.com

我的 Nginx /etc/nginx/sites-available/default:

    server {
      server_name mydomain.com;
      location / {
        proxy_pass         http://localhost:9000;
        proxy_redirect     off;
        proxy_set_header   Host              $host;
        proxy_set_header   X-Forwarded-For   $proxy_add_x_forwarded_for;
        proxy_set_header   X-Forwarded-Proto $scheme;
      }
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/mydomain/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/mydomain/privkey.pem; # managed by Certbot
    include /etc/letsencrypt/options-ssl-nginx.conf; # managed by Certbot
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # managed by Certbot
}
    server {
    if ($host = mydom) {
        return 301 https://$host$request_uri;
    } # managed by Certbot
      listen 80;
      server_name mydomain.com;
    return 404; # managed by Certbot
}

docker-compose.yml (nginx):

      - relay

system.internal-url-前缀:

sentry.conf.py :

CSRF_COOKIE_SECURE = True

有什么我可能遗漏的想法吗？
