If you have a cPanel hosting and your control panel or webmail is not loading from your end, you might need to check whether the corresponding ports are blocked or not by your ISP.

The ports are given below:

Port 2082 -> Cpanel default port
Port 2083 -> Cpanel over SSL
Port2086 ->  Cpanel Webhost Manager (default)
Port 2087 -> Cpanel Webhost Manager over SSL
Port 2095 -> Cpanel Webmail
Port 2096 -> Cpanel webmail over SSL

Run the following commands after launching the command prompt from your local machine to check whether your ISP blocks port.

For checking cPanel ports:

telnet my-domain-name.com 2083
telnet my-domain-name.com 2082

For checking Webmail ports:

telnet my-domain-name.com 2095
elnet my-domain-name.com 2086

If the test is successful, you should receive the following message:

telnet yourdomainname 2083
Trying 89.187.85.9…Connected to yourdomainname

If you get a message saying that the connection is refused, you might need to get in touch with your ISP to open the corresponding ports.

Here’s how to do it, depending on your OS, launch your command prompt:

Windows 8 users – > From the Start screen type cmd and press Enter.

Windows Vista and 7 users -> a) Click Start. b) Type cmd and press Enter.

Windows NT, 2000, and XP users -> a) Click Start. b) Click Run. c) Type cmd or command and press Enter.

In Mac, the terminal is located under your Mac HD -> Applications -> Utilities -> Terminal

In Linux -> Click Application -> Accessories -> Terminal.
