   By default, WordPress considers ports 80, 8080 and 443 as “safe”.

   Example code snippet of changing allowed ports to 80, 8080, 443 and 3000:

   add_filter( 'http_allowed_safe_ports', 'wpdocs_allowed_ports' );
   
   function wpdocs_allowed_ports( $ports ) {
       $ports = array( 80, 443, 8080, 3000 );
   
       return $ports;
   }
