CPanel and FTP login-invalid failure issues

Please forgive my obvious ignorance, but I am now desperate and hopeful that you guys can help.

I am suddenly unable to log in to either (both) the CPanel and FTP for my domain, but only when I use my primary desktop machine. Neither can I access my email accounts for those domains using Windows Live Mail. I can access all just fine if I use a different machine borrowed from a friend and connected to the same IPv6 address (disconnecting the Time Warner cable from my machine and plugging it into the borrowed machine). We've done all the usual fixes described elsewhere on this forum, including and especially adjusting the CPHulk Brute Force Attack blocking and whitelisting my IP address. Nothing works. The primary desktop machine will open the CPanel log in page, but entering the correct username and password results in "Login Invalid." Yes, the host administrator did try resetting all passwords, but same results occurred.

The hosting servers were recently changed out and a new IPv6 address was assigned to my domains, replacing the previous IPv4 address. At the same time, the hosting administrator installed CPanel for the first time (they did not previously use this particular software).This issue started only AFTER the new IP address was assigned and CPanel was installed. But as above, the hosting company has exhausted every avenue they know of to resolve the problem.

At the same time, I purchased a new Motorola/Arris Model SB6121 modem, but I no reason to believe that is related since the failed password issue affects only a single receiving IP address (two domains/websites are shared by that one IP address, and both are affected). Passwords for every other site, including this one, work just fine.

We now have to assume that the issue lies within the one primary machine that I am using. I would rather not have to go out and buy a whole new machine simply to resolve this one issue. Standard Norton Security software turns up no issues.

What am I missing? Is there some setting on the desktop that I need to adjust to make it compatible with CPanel, but that neither I nor my hosting administrator know about?

I can access the websites themselves without difficulty. It is only the CPanel and FTP for those sites that are inaccessible, as well as the email using WLM. All attempts result in "Invalid password" (WLM) or "Invalid Login" (CP, FTP) despite using the correct information.

I have preformed multiple DNS flushes without any change in the problem. I am using a Dell PC running Windows 7.

Any help anyone can offer will be most gratefully appreciated.

Hello,

Have you tried to disable CPHulk on your server ? I think you are getting this issues due to CPHulk Brute Force protection, So please try to disable it and check it again.
Thanks, but as noted in the first paragraph of my query, the host administrator "adjusted" CPHulk and also put my IP address on the "white list." The problem persists even after that. Since none of his other clients are experiencing the same problem, I do not know that he wants to disable CPHulk completely for the entire server. And I do not myself know whether it can be selectively disabled for individual domains on a server handling multiple domains (but I will ask him).

Hello :)

Could you have your provider review /usr/local/cpanel/logs/login_log and /var/log/messages for your IP address to see the specific output when you fail to authenticate?

Thank you.

Do any of the previous replies to this thread help? Do you have root access to the server? If not, you may want to check with your hosting provider to see if they can take a closer look.

Thank you.

You may want to ask them to review the cPHulk logs to verify if the account is locked out due to brute force attempts.

Thank you.
