    The error appeared in the situation where the server was transferred.
    Is this the part where I need to set up the firewall separately?

    Hi @gnjang

    Thanks for reaching out and we’r sorry to hear that you’re running into issues after a server transfer.

    Please kindly know, that the “Could not connect to SMTP host” error indicates that the server refuses connection and it is not able to connect to the remote mail server.

    You’ll need to contact your SMTP/hosting provider with that error report to fix the server configuration or to see if anything is blocking. They’d hopefully be able to help!

    We apologize, but we can’t perform any fixes on our end since it’s SMTP/hosting-related.

    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 settings. In cases where ongoing issues arise while using the Other SMTP mailer, we generally recommend switching to a transactional mailer option if possible.

    In case it helps, we have documentation on setting up each of the available mailers here:?https://wpmailsmtp.com/docs/a-complete-guide-to-wp-mail-smtp-mailers/.
