Impossible d'établir une connexion avec l'hôte mailtrap.io [php_network_getaddresses: getaddrinfo failed: hôte inconnu. #0]

Je suis d'erreur ci-dessous:

Impossible d'établir une connexion avec l'hôte smtp.gmail.com
[php_network_getaddresses: getaddrinfo failed: hôte inconnu.

0]

Mon .env fichier ressemble à ceci:

MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=xxxxxxxxxxxxxx
MAIL_PASSWORD=xxxxxxxx
#MAIL_ENCRYPTION=null

Mon mail.php fichier à l'intérieur de config ressemble:

Étonnamment, je suis en utilisant ce pour les 6 derniers mois et il n'a pas d'erreur plus tôt, mais maintenant quand je l'ai transféré mes construit à nouveau sur la mise en scène j'ai eu cette erreur.

Toutes les suggestions sont grandement appréciés.

vous n'avez pas à fournir mail des informations d'identification .fichier env tous les set null
l'inscription à https://mailtrap.io et d'obtenir le nom d'utilisateur/mot de passe, comme dit ici : code.tutsplus.com/tutorials/...
J'ai mis à jour ma question. Je suis maintenant à l'aide de différents détails.
dans votre .env fichier, ajoutez le code suivant et essayez de nouveau MAIL_DRIVER=smtp MAIL_ENCRYPTION=tls
