Connection could not be established with host smtp.mailtrap.io [Unable to find the socket transport "null" - did you forget to enable it when you configured PHP? #32588] code example

Example: Connection could not be established with host smtp.gmail.com :stream_socket_client(): unable to connect to tcp://smtp.gmail.com:587 (Network is unreachable)

I solved my problem in cpanel using the code:

inside `.env` file change 

	MAIL_DRIVER=smtp 
to
	MAIL_DRIVER=sendmail
