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:

Code:
mysqladmin processlist;
Also, if it's running, try running the following command to see if the database is corrupted:

Code:
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 ?

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.
