    My emails stopped sending out, and I attempted to re-connect my SMTP info in order to troubleshoot. Now, when I enter my info, I’m getting an error in the log when I try to send a test about a wrong version # for SMTP.php.

    My WordPress, WooCommerce, and SMTP plugin are all fully updated.

    Here is the log:

    Debug:
Email Source: WP Mail SMTP
Mailer: Other SMTP
SMTP Error: Could not connect to SMTP host. Failed to connect to serverSMTP server error: Failed to connect to server

SMTP Debug:

    Hi @eckstein

    Thanks for reaching out and we’re sorry to hear about the issue your are experiencing with the Other SMTP mailer.

    Thanks for reaching out! The issue you ran into with the SMTP connection was a serverside issue. Essentially, PHP was unable to make an SMTP connection to your SMTP server due to an error with the SSL certificate. This is not something we would be able to address, as it’s more in your hosting company’s field.

    Please reach out to your website hosts support team.

    Also please know, that the Other SMTP mailer option does not use a dedicated API, which can lead to potential errors based on your website hosting/SMTP settings. In cases where ongoing issues arise while using the Other SMTP mailer, we generally recommend switching to a transactional mailer option (it’s all mailers except the Other SMTP and Default (none) option).

    WP Mail SMTP has documentation on setting up each of the available mailers here: https://wpmailsmtp.com/docs/a-complete-guide-to-wp-mail-smtp-mailers/.
