  • Resolved thehappylittleeater


    I’m getting an error message stating: SSL: no alternative certificate subject name matches target host name ‘’
    I’m being told my Jetpack is out of date and it’s not connecting to WordPress.
    Help would be greatly appreciated!!!

    Hi @thehappylittleeater!

    While your site isn’t using an SSL certificate, it appears that your WordPress settings are using ‘https’ prefixes.

    Could you check the WordPress Address (URL) and Site Address (URL) on your dashboard’s Settings -> General page?

    Make sure they have ‘http’ rather than ‘https’.

    Let me know if we can help further!
