SMTP error from WP smtp Plugin

I'm using Wordpress and want to automate my email by using Wordpress SMTP Plugin to Zoho. I have entered the values correctly, but can not connect to zoho.

I've left attachments.

 the values I put were:

smtp.zoho.com
465
SSL: Yes
SMTP: Yes
(login and password for my Zoho Mail entered correctly)
