After this date, webhooks that fail the SSL certificate verification will not successfully deliver to their hosts. *** Please make sure that your server is correctly configured to support HTTPS with a valid server certificate. We suggest using a [SSL checker](https://www.sslshopper.com/ssl-checker.html) to help you diagnose any problems with your SSL certificate installation.
