To access cPanel’s web-based control panel, you will need to access a non-standard port. The default cPanel port is 2082 for unencrypted connections and 2083 for encrypted. You do not have to append this port number to your URL, as your normal cPanel URL (yourdomain.com/cpanel) should redirect to it. In some cases, however, it may not work. In the event that it does not work, there are a few possible causes.
1. Your firewall is blocking it. This is the easiest to fix. If your firewall blocks cPanel’s port, all you have to do is open that port and proceed as normal.
2. Your ISP is blocking it. This is a bit more difficult. If your ISP is blocking cPanel’s port, you may need to find an alternative method of accessing it. Depending on your web host and the configuration it offers, you should be able to use an alternative URL to access cPanel through port 80 (the standard web port).
3. Your office is blocking it. If you run the office, you should be able to unblock it rather easily. If you do not and you can still justify using your cPanel installation during work hours, you should talk with your supervisor about getting it unblocked.
If you are still not able to access cPanel, you may have to use SSH tunneling, a proxy, or a VPN to access your website’s control panel. You can find free and premium options for all of these solutions.
