I am using Laravel's auth functionality. It's working fine except Forgot Password. I am trying to override following on ForgotPasswordController.
public function showLinkRequestForm()
{
    return view('admin.forgot');
}
It loads the form view for reset password and URL as follows:
$this->get('password/reset', 'Auth\ForgotPasswordController@showLinkRequestForm')->name('password.request');
But when pressing submit button putting email address it shows following errors:
Expected response code 250 but got code "530", with message "530 5.7.1 Authentication required
For your kind information, I didn't make any change without DB connection at .env file.
How can I send a reset link to the email address?
I hope someone will be able to help me with this.
