Balena devices were unable to connect to Cloudlink on February 10, 2026, from approximately 02:26 GMT to 07:11 GMT due to an expired server certificate. Devices that were already connected to Cloudlink were unaffected unless the connection was terminated.
Root Cause: The Cloudlink servers were using an expired certificate that was due for replacement. Consequently, incoming Cloudlink connections failed with a certificate verification error.
Resolution: The certificate has been replaced, and Cloudlink servers were restarted to use the new certificate. Balena devices are expected to reconnect to Cloudlink within a few minutes after being disconnected due to the restart.
