General Update: Upcoming Changes to Let’s Encrypt’s Chain of Trust

A significant update from Let’s Encrypt, one of our integrated Certification Authorities (CA), may affect how customers access your website. On June 6th, 2024, Let’s Encrypt end-users on very old devices or software may receive insecure warnings or be blocked from accessing your applications. To protect your customer experience, we encourage you to confirm which CA you’re using. If it’s Lets Encrypt and serving this type of traffic is a hard requirement, consider changing your TLS subscription to Certainly.Learn more about the change and how to confirm your CA here.
