The trans-id ensures that:
This article provides a deep dive into the causes of this error and offers a comprehensive, step-by-step guide to resolving it.
The error frequently points to an external sync issue. During the SWIM download request, Cisco Catalyst Center reaches out to cloud APIs. If the upstream cloud provider experiences a glitch or returns mismatched session parameters, the connection breaks. The platform receives an invalid metadata_trans_id token back, forcing the task to abort. 2. Expired Trustpool Bundles and Certificates
Follow this step-by-step guide to diagnose the root cause:
Understanding why this error happens is key to selecting the right fix. The four main triggers are:
Expired or missing root certificates in the Trustpool can prevent secure communication with Cisco API endpoints.
If a EULA is needed, accept it there, then try the download via DNA Center. 4. Workaround: Manual Image Import (Immediate Fix)
: Ensure your Cisco.com (CCO) credentials are correctly configured in the system settings and that the appliance has verified HTTPS reachability to Cisco's servers. KGV & Trustpool Updates : Verify that your Known Good Values (KGV) certificates are up to date under System > Settings
If the above steps don't resolve the issue, you can try the following advanced troubleshooting steps:
: Misconfigured proxies or expired certificate chains in the Cisco DNA Center Trustpool can prevent successful API calls to api.cisco.com . Recommended Workarounds
Using the same trans-id from multiple NCS instances (e.g., in a cluster) can invalidate it. Cisco’s servers treat this as a replay attack.
Check the synchronization status. If it shows failed or empty, trigger a manual verification update directly from Cisco.
: Older appliance software releases attempting to connect to Cisco backend servers using deprecated TLS or handshake variables. Immediate Workarounds
