Getting error while trying to send email in localhost php

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

    'default' => [
        //**'className' => MailTransport::class,
        /*
         * The following keys are used in SMTP transports:
