SSL + proxy_pass = 404？

Question

每个人的收获。
在nginx-1.13.8上配置Windows Server时遇到麻烦。 在reverse_proxy上添加SSL后，我收到404

工作配置（http）：

server {
    listen      80;
    server_name example.com;

    location / {
        proxy_pass    http://192.168.0.3:80;
        proxy_set_header Host      $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

使用ssl进行配置：

server {
    listen      443 ssl;
    server_name example.com;

    ssl                     on;
    ssl_certificate         ../cert/certcombined.crt;
    ssl_certificate_key     ../cert/private_rsa.key;


    location / {
        proxy_pass    http://192.168.0.3:80;
        proxy_set_header Host      $host;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $remote_addr;
        proxy_set_header X-Forwarded-Proto $scheme;
    }
}

192.168.0.3在Linux上是Apache
