SQLSTATE [HY000] [1130] Host ‘localhost’ is not allowed to connect to this MariaDB server

I’m using windows 11 and  PhpMyAdmin on the XAMPP server. Once while working, the MySQL server  and PHPMyAdmin stop working with this error:


It’s due to a crash of the User table in the MySQL database. The solution is straightforward. Just go through the following steps:

  • Open XAMPP control panel
  • Click MySQL > Config > my.ini

Add below line under [mysqld] tag. if the [mysqld] tag not exists then you can create a new one.

Save my.ini

Restart MySQL server by pressing the STOP and START button
