You need to wait few minutes before it can start working on HTTPS port, no restart required.

Now netstat shows nginx runs on port 80

[root@correo ~]# netstat -lntp| grep 80
tcp        0      0 0.0.0.0:80              0.0.0.0:*               LISTEN      90391/nginx: master 
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      22891/java          
tcp6       0      0 :::7780                 :::*                    LISTEN      24005/httpd
