## AI overview

The article explains upcoming compatibility problems caused by the expiration of Let's Encrypt's DST Root CA X3 certificate. Modern browsers and devices should continue working through the ISRG Root X1 certificate, but older devices may fail to connect to secured websites and APIs. It also describes an Android workaround that can trigger failures in some OpenSSL, GnuTLS, and LibreSSL-based IoT devices, and notes that Forge supports preferring ISRG Root X1.

## Source excerpt

On Thursday, September 30th there will be a small change in how older browsers and devices will treat Let's Encrypt's certificates. While most sites will be unaffected, it will likely impact you if you're providing an API or support IoT devices.
