    Hello

    I’m seeing this error when attempting to use your plugin:

    SMTP Error: Could not connect to SMTP host. Connection failed. stream_socket_enable_crypto(): Peer certificate CN=net.netcoservers10.com' did not match expected CN=smtp.titan.email’

    The SMTP servers are not seeing any signal from our web server, and the web server hosting admins say that this could be happening due to a name server mixup on your end.

    Any help much appreciated.

    Best

    Alex

    Hello @alexandertimothy,

    As per the error message, it seems like there’s a mismatch between the expected CN (smtp.titan.email) and the actual CN (net.netcoservers10.com) of the peer certificate. This could be caused by an invalid or misconfigured SSL certificate on the SMTP server.

    To resolve this, please check and verify if your PHP has OpenSSL support enabled. Ensure that the “extension=php_openssl” extension is enabled in your php.ini file.

    If OpenSSL support is enabled, the next step would be to replace the invalid certificate with a valid one. This involves generating a new SSL certificate and installing it on the SMTP server.

    If you’re using a shared hosting provider, please reach out to their support team for assistance with generating and installing the SSL certificate.

    Once you’ve replaced the certificate, please try sending an email again and let us know the update.
    I’ll be here to further assist you.
