In the recent versions of Hestia CP, developers have disabled the ability to access PHP MyAdmin using the server's IP address (http://ip/phpmyadmin/) for security reasons.
Instead, it is now necessary to use https://host.domain.tld/phpmyadmin/, where the server must be associated with at least one domain, and it should resolve. Please note that for our VPS services, we recommend using our DNS: ns1.whs.ee, ns2.whs.ee, which can be specified for your domain. When using our DNS, it is also necessary to create a zone for your domain in the user control panel "Services --> DNS Manager," specifying the domain name and the IP address of your server.
However, even with the correct NS settings, when accessing https://host.domain.tld/phpmyadmin/ or clicking the "PHP MyAdmin" button in the Hestia CP panel, users may encounter the error "Error Existing configuration file (/etc/phpmyadmin/config.inc.php) is not readable."
To fix this error, you need to connect to the server via SSH with root privileges and execute the following command:
chown -R root:www-data /etc/phpmyadmin/
