Rất đơn giản để sửa lỗi không truy cập vào port khi cài ssl vào domain chính trong hocvps.
Bạn chỉ cần thêm đoạn code sau vào file zubi.cloud.conf theo đường dẫn sau:

/etc/nginx/conf.d/zubi.cloud.conf

Đoạn code cần thêm:

server {
listen 2018 ssl;

  access_log        off;
log_not_found     off;
  error_log /home/zubi.cloud/logs/nginx_error.log;

     root /home/zubi.cloud/private_html;
index index.php index.html index.htm;
     server_name zubi.cloud;

        error_page 497 https://$server_name:$server_port$request_uri;
