In order to access your Plesk control panel, as long as the server is completely operative, you only have to use the following URL from any browser (Chrome, Explorer, Opera, FireFox, etc.):
https://IP.de.tu.servidor:8443
Note:
Remember to replace IP.of.your.server with the IP server you wanto to access.
If you have a domain pointing to your server you can also use it to access your Plesk control panel from the following URL:
https://yourdomainname.com:8443
Una vez se abra la página aparecerá un mensaje similar a:
The connection is not private[…]
This message is normal, since you are trying to access through the SSL protocol on a page with no SSL certificate setup. You only have to indicate that you want to continue and the access panel page will show up.
