We have updated the Adafruit IO SSL/TLS certificate.
If you are having issues connecting, please ensure you have the latest Adafruit IO Arduino library versionby navigating to the Arduino Library Manager (from the Arduino IDE, navigate to: Sketch -> Include Library -> Manage Libraries):
The certificate is fingerprinted in that library and you will have issues connecting if that library is out of date. The current version with the latest fingerprint is 3.7.0.
In the future, we will announce this much further in advance to ensure everyone is aware of the scheduled certificate updates to reduce downtime. The next update will be in approximately 2 years.
