Database Error Connection Failed in RoundCube cPanel

June 11, 2022 / / 0 Comments

RoundCube is a client based on Web IMAP and that is very easy to install & configure. RoundCube is open-source and free software that is subject to General Public License that except plugins and skins. The main feature of Roundcube is that all data are stored in the database and it does have the interface of the desktop. RoundCube has the well-known feature of the prevalent usage of Ajax technology.

Occasionally we might receive an error message, whenever RoundCube webmail tries to connect with its database. And the error occurs in cPanel server like “database error failed, unable to connect to the database. Please contact your server-administrator”.One of the main reasons for such an error is that the mailbox could have been getting corrected.

Here in this section, we are going to show how to overcome RoundCube database errors and how to fix the issues as well.

Fixing Database Error – RoundCube Webmail:

It is always advisable to check the database, server status and assure it is running and active. We can use various methods to resolve the problems. They are as follows,

Method 1: Restoring with the previous version of the mailbox database is one of the recommended and easiest ways to solve the issues.

Below mentioned the process to fix and restore the previous version of the mailbox database:

  • Either go to the folder of cPanel ‘/home/<cpanel_user>/etc/<domain>/’ and change the name of the file from <email_user>.rcube.db to <email_user>.rcube.db.bakor moving it out of that folder.

Change the name of the file from<email_user>.rcube.db.<number_stamp> (make use of the most recent copy based on the timestamp) to <email_user>.rcube.db.And now here we go, try to access your RoundCube.

Method 2: Another method of fixing an issue without restoring the previous settings is to restart the RoundCube from the beginning.

The following procedure shows how to fix this issue:

  • Either change the name of the file from <email_user>.rcube.db to <email_user>.rcube.db.bak or moving it out of that folder.

And now you can try to access the RoundCube again.

Normally for database storage like contacts, information, and other details, RoundCube makes use of SQLite or MySQL. Due to this, it is mandatory to RoundCube needs to be connected to its database in order to pick up the information. And in case of failure on the database connectivity may cause a “database error connection failed” error message displayed in the cPanel server. Using the different methods mentioned above we can overcome these kinds of issues.

cPanel login invalid while using correct username and password

April 29, 2022 / / 0 Comments

Sometimes you may get login invalid error while trying to login to your cPanel account. But the username and password that you are entering is correct. This will happen because of your IP address is blocked by cphulkd for BruteForce.

What is cPHulk ?

cPhulk is a similar feature like Firewall, with cphulk cPanel will give you and extra measure of protection from attacks like bruteforce.  Suppose someone is trying to compromise your server using random failed logins

So from the above description you can see that this is an important feature of cPanel/WHM so disabling this feature will not be a good idea, instead  you can white-list your IP address on the BruteForce protection. So it will allow connections from your IP address.

You can see the errors related to blocked connections by cphulkd for BruteForce from the cPanel error log itself,

/usr/local/cpanel/logs/error_log

And the error will be like pasted below,

main::badpass('faillog', 'brute force attempt (user iserversupport) has locked out IP xxx.xxx.xxx.xx...', 'skip_hulk', 1, 'msg_code', 'invalid_login') called at cpsrvd-ssl line 5790
        main::connect_cphulkd() called at cpsrvd-ssl line 5255
        main::handle_form_login() called at cpsrvd-ssl line 1131
        main::handle_one_connection() called at cpsrvd-ssl line 996

You can simply white-list the IP address on cphulkd by using the following script,

/scripts/cphulkdwhitelist

This script can be used along with the IP address that you need to white-list. See the sample command below,

/scripts/cphulkdwhitelist <IP-Address-for-whitelist>

This will allow your IP address through cphulk and now you will be able to login to the cPanel using correct password.

You can also do this from WHM. For that login to WHM and go to,

Home >> Security Center >> cPHulk Brute Force Protection

There will be options to  White/Black list IP addresses on cPHulk Brute Force Protection.
