Symptoms

During upgrade pre‑check in SDDC Manager, one or more of the following errors appear:

  • "NSX audit not connected compute managers"
  • "NSX audit not connected transport nodes"

In NSX Manager, affected transport nodes may show a degraded status.

Cause

These errors occur when NSX components required for upgrade validation are not in a healthy connectivity state:

  • The Compute Manager connection in NSX is DOWN.
  • One or more Transport Nodes have connectivity failures or show a degraded operational state.
  • Stale connectivity information may exist in SDDC Manager or vCenter

Resolution

Perform the following steps to remediate the issue:

  1. Resolve transport node connectivity issues in NSX, ensuring all impacted nodes return to a healthy state.
  2. Confirm that the Compute Manager connection is UP in NSX Manager.
  3. Restart the SDDC Manager appliance and vCenter Server.
  4. Rerun the SDDC Manager upgrade pre‑check.
  5. If failures continue, perform a rolling reboot of the NSX Manager cluster, rebooting the node hosting the VIP last.
