If the mysql server is on the same server as your application use host as localhost
DB_HOST=localhost

Rapid Authentication and Configuration in Laravel 5.4

I'm trying to add authentication to my Laravel project. My database configuration is:
'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8mb4',
'collation' => 'utf8mb4_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],
And the .env file contains:
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=example
DB_USERNAME=root
DB_PASSWORD=
When I try to register, this error happens:
I'm using XAMPP and my phpMyAdmin table structure is shown in this picture:

Its because remember_token field is not allowing to store null.
so either you need to provide value for remember_token or allow remember_token to have null values.

Please help.

Your screenshot shows "localhost" and your code shows "127.0.0.1". MySQL treats "localhost" and "127.0.0.1" differently.
Make sure you have granted appropriate permissions for 'root'#'localhost' in your database.
