Question

nginx有一个非常奇怪的问题：我在AWS服务器上使用Python运行一个非常基本的flask / gunicorn应用程序，并且我对有效端点的许多请求都收到404（大约一半）。

我已经做了一些尝试来将问题隔离到nginx。我翻阅了

/var/log/nginx/access.log

这是输出：

在此代码中，我反复向/路由发出GET请求，该请求仅返回一个字符串。我调查了404 209，但无法准确确定为什么会偶然发生此错误。该服务器在一个AWS实例上运行，只有一小部分用户，当时没有人提出请求。

错误日志（位于/var/log/nginx/error.log）为空。

这是我当前用于nginx的.conf文件：

server {
        listen 443 ssl;
        listen [::]:443 ssl;

        server_name DOMAIN.com www.DOMAIN.com;

        location / {
                proxy_pass http://127.0.0.1:8000/;
        }

    ssl_certificate /etc/letsencrypt/live/DOMAIN.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/DOMAIN.com/privkey.pem; # managed by Certbot

}

server {
    if ($host = www.DOMAIN.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot


    if ($host = DOMAIN.com) {
        return 301 https://$host$request_uri;
    } # managed by Certbot

        listen 80;
        listen [::]:80;

        server_name DOMAIN.com www.DOMAIN.com;

        return 301 https://$server_name$request_uri;

}

有什么提示吗？谢谢！

Flask服务器-有效端点大约有一半的时间出现404错误
