  • Hi @bs1kim,

    The error indicates that it is unable to contact the SMTP server you have specified in the Host property. There could be various reasons for this such as firewall blocking, the next best step is to contact your host with this error log. Alternatively, if you host is unable to find the issue, you can choose other available mailer options. We have documentation for each of the available mailers.

    I hope this helps!
