    Assuming the cPanel installation was successful, simply restart cPanel using this command:

    /etc/init.d/cpanel restart

    Or reboot the server (not recommended).

    For HTTP its port 2086. Port 2087 is for SSL (HTTPS)

    Use these links:

    http://91.121.24.67:2086 or https://91.121.24.67:2087

    That still doesnt work however, try flushing out your iptables rules:

    iptables -F

    cPanel's cpsrvd responds to either SSL or non-SSL requests on port 2087. cpsrvd should give a clue either way.

    Find the open and closed of your server ports using the below command

    #nmap localhost
    #nmap ip-Address

    Also Check is it connected from out side and inside

    eg)
    [email protected]:~$ telnet xx.xx.xx.2\xx 2082
    Trying xx.xx.xx.xx...
    Connected to xx.xx.xx.xx.
    Escape character is '^]'

    Is it not connected means try to reinstall cpanel, In default cpanel port open automatic on installation time.

    Do you have it open with iptables?

    Well if you flush iptables and you have default deny it will lock you out until reboot.

    Are you getting connection reset or connection timeout?

    you would do iptables -L -n to see your iptables rules. If it is default centos webserver I think it does come with some default rules, just install a firewall like csf and configure it for the open ports would be easy way.

    connection reset usually means the daemon (whm) is not running or your default deny is reject but I would assume it is drop so if it is firewalled you would get a connection timeout.

    Make sure cPanel is installed successfully. I even didn't get Apache Success page while browsing http://91.121.24.67. If cPanel is installed successfully and Apache is up and running, you should get "Apache is working on your cPanelŽ and WHM™ Server" page.

    Do you have an firewall installed? CSF, AFP?

    Try doing

    # iptables -F

    You can try after,

    service iptables stop
    service apf stop
    csf -f

    Running a telnet on the IP address 91.121.24.67 on the ports 2082/2083 resulted in a connection refused message.

    Performing a port scan on the IP address reveals cPanel ports are not being filtered nor are running.

    Are you sure the cPanel service is running ?

    ps aux | grep cpsrvd
    Secondly, is this a VPS wherein the server might be running out of memory. Can you paste the output of the following command,

    tail -f /var/log/chkservd.log

    Try to open the port using the iptables as given below,

    #iptables -A INPUT -p tcp --dport portno -j ACCEPT

    and/or

    #iptables -A OUTPUT -p tcp --dport portno -j ACCEPT

    after that save and restart iptables using command,

    #service iptables save
    #service iptables restart
