Resolution

WARNING! The below solution represents only a hint. Portal administrators shall perform NGINX configurations at their own discretion. Liferay Support is limited in assisting with the below topic.

• Following the nginx official documentation, you may be able to achieve the expected behavior by having a configuration like the one below:
  
  

  server {
      listen 80;
      server_name mydomain.com;
      return 301 $scheme://www.mydomain.com$request_uri;
  }

  in the nginx.conf file.
