CSCwa82309 | x509: certificate signed by unknown authority |
The Secure Sockets Layer (SSL) certificates issued from the QuoVadis root certificate authority (CA) trust chain before March 31, 2021 cannot be renewed from this CA. The QuoVadis Root CA 2 certificates on the Cisco AI Network Analytics cloud expire in March 2022. After March 1, 2022, Cisco DNA Center will fail to establish a secure connection with the Cisco AI Network Analytics cloud. As a result, all Cisco DNA Center AI Analytics and AI Endpoint Analytics features will no longer function.
The QuoVadis Root CA 2 Public Key Infrastructure (PKI) certificate used by Cisco DNA Center software is subject to an industry-wide issue that affects revocation abilities. Due to this issue, no new QuoVadis Root CA 2 certificates will be issued or renewed by Cisco after March 31, 2021. This affects certificate renewals on Cisco devices, Cisco cloud servers, and third-party services.
Certificates issued before the QuoVadis Root CA 2 was decommissioned will continue to be valid. However, the certificates will not renew when they expire.
The QuoVadis Root CA 2 certificates used by Cisco AI Network Analytics cloud expire in March 2022. Those certificates will be replaced with new ones on March 1, 2022 from a different root CA. After the certificates are replaced, affected Cisco DNA Center clusters will fail to establish a secure connection to Cisco AI Network Analytics cloud. This will cause Cisco DNA Center AI Analytics and AI Endpoint Analytics features to stop functioning.
The following features are impacted by this problem:
The secure connection from Cisco DNA Center to the Cisco AI Analytics cloud will fail. The connection failure can be observed from the Cisco DNA Center user interface and in logs.
Cisco AI Analytics Settings page
Choose Cisco DNA Center UI > System > Settings > Cisco AI Analytics.
Cloud is currently unreachable
AI Analytics Trends and Insights
Example: Heatmap
Choose Cisco DNA Center UI > Assurance > Trends and Insights > Network Heatmap.
Oops! There is an error fetching data.
AI Analytics agent logs
The agent logs can be collected through these steps.
$ magctl service logs -a ai-network-analytics kairos-agent
"x509: certificate signed by unknown authority".
There is no manual workaround.
A software fix is available for this problem. The fix corrects the Cisco DNA Center software to include the new Identrust Commercial Root CA 1 certificate used by Cisco AI Network Analytics cloud after March 1, 2022. Cisco recommends customers upgrade their affected Cisco DNA Center appliances to one of the following versions with the fix:
