I have tried send mail by
MAIL_PORT=587 MAIL_ENCRYPTION=tls
AND
MAIL_PORT=465 MAIL_ENCRYPTION=ssl
And I allow the option "less secure app"
But always get this notification: Connection could not be established with host smtp.gmail.com :stream_socket_client(): unable to connect to tcp://smtp.gmail.com:587 (Connection timed out)
My Laravel Version is Laravel Framework 8.34.0 and using ubuntu 18.04
How can I fix this problem Thanks everyone
