This issue appears on the Hestia Control Panel (HestiaCP v1.5.10) running under distro flavours Debian 11 (Bullseye) with MariaDB 10.6.7 Database Server installed on the machine. This Bare-metal server having 64GB Memory (RAM), 16 CPU Cores and 1TB Storage with Software RAID 1. It running under configurations of Apache/2.4.52 (Debian) with mod_fcgid/2.3.9 and OpenSSL/1.1.1k, Nginx Reverse Proxy, and PHP Version 7.4.28. Where the error logs are as follow, it I found when try to login into the phpMyAdmin.
Cannot log in to the MySQL server

To solve this issue simply enable MariaDB 10.6 database server (mysql.service) with the following command:
$ systemctl enable mysql.service
After that you need to secure your MariaDB Installation using the below command and make sure to set proper root password for the MySQL administrative account (superuser privileges).
