SMTP Prestashop connection failed

SMTP Prestashop connection failed

Hello, I have configured my email correctly. But I have a problem configuring the email with my Prestashop store

smtp server - smtp.zoho.com
smtp user - your email address configured in Zoho
smtp password - password of the corresponding Zoho account
port and encryption - 587 with TLS (or) 465 with SSL

With TLS 587 encryption I get this error:
Unable to connect with TLS encryption




If I connect with SSl 465:

Connection could not be established with host smtppro.zoho.eu :stream_socket_client(): SSL operation failed with code 1. OpenSSL Error messages: error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed



There it asks me for some type of certificate, do I have something left to configure for the mail to work?
