Issue Getting error connect to server at 'localhost' failed

[tempus77]

Hello, i am getting this error on my email:

/etc/cron.daily/logrotate:
mysqladmin: connect to server at 'localhost' failed
error: 'Access denied for user 'root'@'localhost' (using password: NO)'
error: error running shared postrotate script for '/var/log/mysql/mysql.log /var/log/mysql/mysql-slow.log /var/log/mysql/mariadb-slow.log /var/log/mysql/error.log '
run-parts: /etc/cron.daily/logrotate exited with return code 1

Does anyone know what could cause this and how could I fix it?
Thanks

Have a look here: Messages about failed logrotate task are received in Plesk on Ubuntu 18 or Debian 9: 'Access denied for user 'root'@'localhost' (using password: NO)
