Hi !


After I upgrade the Security Center from 13.0 to 13.1, the email notification do not work anymore with this error :


Erreur du temps d'exécution : Cannot send notification by e-mail.
. #1893 Erreur Curl 'SSL peer certificate or SSH remote key was not OK'.

Détails de l'erreur : 1893/0 (Curl error: 0), c:\a\b\a_8jxwdohs\s\csadminkit\development2\common\mailer\smtp.cpp, 1214..


I use a simple smtp server (port 25 without TLS or anythings like that) that’s working great for another software !


Thanks for helping me !


Bye !

Thanks a  lot !

I have the same problem, the sulution was this.


Since version KSC 13.1 the TLS option is in the email notification settings, which is activated by default. I'm guessing the email server isn't configured for TLS. In the e-mail settings you have the option "Do not use TLS" (English version) to deactivate TLS.


Best regards
