    Hello :) This error message suggests that MySQL is not accessible. Are you able to verify if MySQL is running on this server? You can check this with a command such as:
    mysqladmin processlist;
    Also, if it's running, try running the following command to see if the database is corrupted:
    mysqlcheck cphulkd
    Thank you.

    Actually we checked and mysql was down. Our server is Apache on CentOS. I checked on the internet for this and found that I should whitelist the MYsql DB ip in cphulk database. After doing this much again the server went down and we got the following error from logs: Brute force detection active: 580 LOGIN DENIED - TOO MANY FAILURES - IP TEMP BANNED What can be root cause ? and what does this error means ?

    You should not have to whitelist the IP address of your server in cPHulkd. Were you able to get MySQL started again? As far as cPHulk, it's normal for it to block brute force login attempts. More information on cPHulk is available at: cPHulk Brute Force Protection - Documentation - cPanel Documentation You may also find this document helpful if you want to manage it via the command line: cPHulk Management on the Command Line - cPanel Knowledge Base - cPanel Documentation Thank you.

    You might check your firewall to insure you've got the proper ports added. You can find the list here: How to Configure Your Firewall for cPanel & WHM's Services - cPanel Knowledge Base - cPanel Documentation

    CSF firewall is enabled on our server and I have checked proper ports are added also. Please let me know what else I can do to make the Cpanels working ? Following I am pasting from my server: >>>>> TCP_IN = "20,21,22,25,53,80,110,143,443,465,587,993,995,2077,2078,2079,2080,2082,2083,2086,2087,2095,2096" # Allow outgoing TCP ports TCP_OUT = "20,21,22,25,37,43,53,80,110,113,443,587,873,993,995,2086,2087,2089,2703" # Allow incoming UDP ports UDP_IN = "20,21,53" # Allow outgoing UDP ports # To allow outgoing traceroute add 33434:33523 to this list UDP_OUT = "20,21,53,113,123,873,6277,24441" <<<<< Thanks.

    Could you open a support ticket using the link in my signature so we can take a closer look? You can post the ticket number here so we can update this thread with the outcome. Thank you.
