Laravel：无法使用2个可能的身份验证器在SMTP服务器上使用用户名进行身份验证

I've configured to gmail SMTP server to send email. Account less secure app turned ON, also Recapture enabled. Here is the mail.php configuration.

This code working fine on local server. But when i tried to in godaddy server i saw the following Error :

 (1/1) Swift_TransportException Failed to authenticate on SMTP server
 with username "xxxx@gmail.com" using 2 possible authenticators in AuthHandler.php (line 181)

.env (mail part)

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=xxxx@gmail.com
MAIL_PASSWORD=xxxxxx
MAIL_ENCRYPTION=tls

Mail.php

return [
    'driver' => env('MAIL_DRIVER', 'smtp'),
    'host' => env('MAIL_HOST', 'smtp.gmail.com'),
    'port' => env('MAIL_PORT', 587),
    'from' => [
    'address' => env('MAIL_FROM_ADDRESS', 'xxxx@gmail.com'),
    'name' => env('MAIL_FROM_NAME', 'xxxx'),
    ],


    'encryption' => env('MAIL_ENCRYPTION', 'TLS'),
    'username' => env('MAIL_USERNAME'),
    'password' => env('MAIL_PASSWORD'),
    'sendmail' => '/usr/sbin/sendmail -bs',
    'pretend' => false,

What should I do now?

This is an old thread, but my resolution was a bit different for the same error. Turns out my Swift configuration is fine. The IP from my server was blocked by Google as suspicious. I was able to clear it by visiting this link, then executing my mailer code from the server. http://www.google.com/accounts/DisplayUnlockCaptcha
