Host is not allowed to connect to this MariaDB server XAMPP

XAMPP is a popular open-source software package that allows developers to set up a local web server environment for testing and developing web applications. One of the components included in XAMPP is MariaDB, a widely used open-source relational database management system.

However, when working with MariaDB in XAMPP, you may encounter the error message, "Host is not allowed to connect to this MariaDB server." In this article, we will explore the causes of this error and provide solutions to resolve it.



Possible Causes of the "Host is not allowed to connect to this MariaDB server" Error:

  1. Access Privileges:

    • This error often occurs due to insufficient access privileges for the user trying to connect to the MariaDB server. Ensure that the user has the necessary privileges to access the database.
  2. Host Restrictions:

    • MariaDB server, by default, may restrict connections to specific hosts. If your host is not in the list of allowed hosts, you'll encounter this error.
  3. Firewall or Port Blocking:

    • A firewall or port blocking issue can prevent the connection between your application and the MariaDB server. Make sure the firewall is not blocking the MariaDB port (usually 3306).
  4. Incorrect Configuration:

    • Check your application's configuration files to ensure that the host, username, password, and port settings match the MariaDB server configuration in XAMPP.
  5. MariaDB Service Status:

    • Ensure that the MariaDB service is running in XAMPP. Sometimes, the server might be stopped or not properly started.
