Cannot manage a switch due to an invalid SSL/TSL certificate

Use this information to troubleshoot certificate issues when managing switches that are running CNOS.

Each device has a self-signed SSL certificate that Lenovo XClarity Administrator uses to communicate with the device through HTTPS. If you delete or regenerate the certificate on the switch, communication between the switch and XClarity Administrator fails and the switch appears offline.

To fix this problem, from the All switches page, select the switch and click All Actions > Security > Resolve Untrusted Certificates.
