Ich habe ein Problem mit SMTP Server (die Einstellungen sind richtig)&nbsp;

Fehlermeldung:

Connection could not be established with host [smtp.yandex.com](http://smtp.yandex.com)&nbsp;[#0] at /var/www/vhosts/\*\*.de/httpdocs/vendor/swiftmailer/swiftmailer/lib/classes/Swift/Transport/StreamBuffer.php:269)"}

&nbsp;

Woran kann das liegen? Bzw irgendwelche Ideen wie man die Ursache rausfinden kann?

Ich benutze Cloudflare mit kostenpflichtigen 5€/Monat&nbsp;SSL.&nbsp;&nbsp;
