Issue/Introduction
- NSX Host Upgrade Fails, and the upgrade status is Not Started.
You recently replaced the certificates after which compute manager is in down state.
Environment
VMware NSX
Cause
Due to a recent certificate replacement, there is a thumbprint mismatch between the Compute Manager and NSX. As a result, the Compute Manager status appears as Down, which prevents the upgrade process from proceeding and triggers the above error.
Resolution
To resolve the Compute Manager “Down” state caused by a thumbprint mismatch after a vCenter Server certificate replacement, follow the below KB article.
After the vCenter Server certificate is replaced, the compute manager connection is "Down" in the NSX UI
