    I’ve tried to setup WP MAIL SMTP but I failed when I sent email test. First, I thought my email smtp is configured wrong, but it doesn’t. I try my email smtp using gmass.co/smtp-test to send email, and it worked.

    Here is the error log from WP MAIL SMTP:

    And this is log from gmass.co that can succesfully sent email:

    Hi @semesta,

    Thanks for reaching out! The error log indicates that you have experienced an issue related to the server certificate. Basically, the current certificate does not match the hostname you’ve configured.

    Please contact your hosting/email provider with the full SMTP error log and they should be able to assist you further.

    I hope this helps. Thanks!

    Thanks for reply @darshanaw !

    I don’t think the problem is on my email provider, because I’ve tried using another smtp plugin (post smtp) and it worked just fine. But if it can be solved, I love to use wp mail smtp more.

    Thanks! And I will still try to contact my email provider
