I am having error while trying to send mail in laravel

Question

I have been sending mail normally before with my laravel mail setup below and it works perfectly. But now when i run the app and try to send mail it shows this error "Connection could not be established with host smtp.gmail.com :stream_socket_client(): unable to connect to tcp://smtp.gmail.com:587 (No connection could be made because the target machine actively refused it."

i have researched and tried different means to setup my laravel mail, but still i get errors, and my Less secure app access for my gmail is turned on.

My .env

MAIL_MAILER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=delivery@gmail.com
MAIL_PASSWORD=mypassword
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=delivery@gmail.com
MAIL_FROM_NAME="${APP_NAME}"

mail.php

'default' => env('MAIL_MAILER', 'smtp'),

Answer 2

Can you check the inbox of the Gmail account you are using as SMTP. Looks like it access may be restricted from Gmail. You may have received the mail related to some app accessing your account. You need to authorize and allow the permissions.
