Test email not sending with G Suite

Replies: 0

I have configured all step by step as shown in this article Gmail documentation , but at this step when i clicked on Allow then i returned to a 404 error page on my site, and given following step not done,

“When you’re ready, click the Allow button to proceed.

Grant permission for site to send email

Next, you’ll be returned to your WP Mail SMTP settings and a success message will be displayed. Now that the connection is complete, you’re ready to send a test email under the Email Test tab.”
