Warning: mysqli_connect(): Error while reading greeting packet. PID=1092 in C:\xampp\htdocs\myprojet\index.php on line 10

Warning: mysqli_connect(): (HY000/2006): MySQL server has gone away in C:\xampp\htdocs\myprojet\index.php on line 10

MySQL can be configured to not accept external connections, for security reasons. By saying the full domain name, you are using the public IP and therefore you are an external connection. If MySQL is running on the same box as your webserver, just access it via this domain name:

localhost:2082
