Cause 1: Incorrect Login Credentials

The most common cause of the “Host is not allowed to connect to this MySQL server” error is incorrect login credentials. This means that the username and password entered in the database connection code are incorrect.

Cause 2: IP Address Restriction

Your hosting provider may have restricted access to your MySQL database by IP address. This means that only authorized IP addresses can connect to the database server. If the IP address from which you are connecting is not authorized, you will see the “Host is not allowed to connect to this MySQL server” error.

To check if your IP address is authorized, you can try connecting to your MySQL database from a different IP address, such as a different location or device. If you are able to connect from a different IP address, your hosting provider may need to update the authorized IP address list.

Fix 2: Contact Hosting Provider

If you believe that IP address restriction is causing the error, contact your hosting provider and ask them to update the authorized IP address list. You may need to provide them with your current IP address.

Cause 3: Firewall or Security Software

If you have firewall or security software enabled on your computer or network, it may be blocking your connection to the MySQL server. This can cause the “Host is not allowed to connect to this MySQL server” error.

To test if firewall or security software is causing the error, try disabling it temporarily and then attempt to connect to your MySQL database.

If you are still unable to connect, you may need to check your firewall or security software settings or contact the software vendor for assistance.
