@neeraj1005 did you turn on less secure app option on your google account?

if you already did that then add this config to mail.php file in your config folder

'stream' => [
        'ssl' => [
            'allow_self_signed' => true,
            'verify_peer'       => false,
            'verify_peer_name'  => false,
        ],
    ],

I have the same issue, and it does work on my local server however not working on the live server.

Edit: It worked afterward, there was some other issue that I can't figure out but it started working and no issue so far.

  1. Login to your gmail account e.g. myaccount.google.com
  2. Go to Security setting and Enable 2 factor (step) authentication
  3. After enabling, Inside the 2 Step Verfication , you can see App passwords option.
  4. Put your app name and click CREATE button to get new app password.
  5. Finally copy the 16 digit of password and click done. Now use this password instead of email password to send mail via your app.
