I'm new to the Wordpress world and just installed the Easy WP SMTP plugin on the website. At the time of sending the test email, I get an error message. The debug info says,

Debug Info
CLIENT -> SERVER: EHLO localhost
SMTP Error: Could not authenticate.CLIENT -> SERVER: QUIT
SMTP connect() failed. https://github.com/PHPMailer/PHPMailer/wiki/Troubleshooting

I added the setting here.

Anyone know what is the issue here?

If you want to configure Gmail account, you need to fill Encryption type: SSL Port: 465 Requires Authentication: Yes

Or you can try https://wordpress.org/plugins/wp-mail-bank/. This would help you in authenticating the Gmail account using oAuth.
