用于多个端口的Nginx反向代理SSL

Question

我已使用nginx反向代理为mydomain.com配置了我的ssl，因此它在https://example.com上可以正常工作，但是我需要相同的ssl证书才能在端口8081上工作，这个https://example.com:8081应该可以工作。

即使经过多次尝试，我也不知道，这是我正在工作的nginx conf

server {


    server_name example.com www.example.com;

    location / {
        proxy_pass http://localhost:8088;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;

    }



    listen [::]:443 ssl ipv6only=on; # managed by Certbot
    listen 443 ssl; # managed by Certbot
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/example.com/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 {
    listen 8081;
    server_name example.com www.example.com;
  location / {
        proxy_pass http://localhost:1260;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }


    }


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


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


    listen 80 default_server;
    listen [::]:80 default_server;



    server_name example.com www.example.com;
    return 404; # managed by Certbot




}

任何帮助都非常感激，因为我真的在这里苦苦挣扎。
