Nginx 配置未读取子域名的位置

Question

你好，我是 nginix 新手，我正在尝试做几件事

1. 如果主域名或子域名不是 https 则重定向到 https

2. 加载/读取相应块的位置配置

3. 加载/读取子域配置而不是主域配置

    server {
   
    if ($host = example.net) {
        return 301 https://example.net$request_uri;
    }
    listen       80;
    server_name  example.net www.example.net;
    return 301 https://example.net$request_uri;
   
    }
   
    server {
   
    if ($host = in.example.net) {
        return 301 https://$host$request_uri;
    }
   
    listen       80;
    server_name  in.example.net;
    return 301 https://in.example.net$request_uri;
   }
   

我的主域配置：

server {
  server_name  example.net;

 location / {

proxy_pass http://myip:8089;
proxy_set_header X-Forwarded-Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;

rewrite ^/$ /app/usa/home break;

}

 listen 443 ssl; # managed by Certbot
 ssl_certificate /etc/letsencrypt/live/example.net/fullchain.pem; # managed by Certbot
 ssl_certificate_key /etc/letsencrypt/live/example.net/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

}

我的子域名配置：

server {
    server_name  uk.example.net;
  
location / {

    proxy_pass http://myip:8089;
    proxy_set_header X-Forwarded-Host $host;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;

    rewrite ^/$ /app/uk/home break;
    
    }
    
     listen 443 ssl; # managed by Certbot
     ssl_certificate /etc/letsencrypt/live/example.net/fullchain.pem; # managed by Certbot
     ssl_certificate_key /etc/letsencrypt/live/example.net/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
    
}

}

问题：当我加载 uk.example.net 时，它会加载/读取主域（example.net）位置配置

1. 我该如何改善？

2. 我做错了什么？

3. 如果我将来有多个子域名，有什么建议？
