SMTP Error.

[Sappy]

The error is this:
SMTP Error: Connection failed: Failed to connect socket: Network is unreachable in /home/<REDACTED>/domains/mail.domain.com/public_html/program/lib/Roundcube/rcube.php on line 1774 (POST /?_task=mail&_unlock=loading1635897530726&_framed=1&_action=send)

Redacted my username and domain. Asked my hosting provider and yes it can connect to the smtp and the port is open.

I am using Yandex mail. This is my config

Code: [Select]

$config['smtp_server'] = 'ssl://smtp.yandex.com.';
$config['smtp_port'] = 465;
$config['des_key'] = 'REDACTED';

Why do you have a "." after .com?

[Sappy]

Removed it, still doesn't work . IMAP does work though.
