Installation of NSX on ESXi host fails due to Compute Manager down

Products

• VMware NSX

Issue/Introduction

• Installation of NSX on ESXi host fails at Configuration complete step.
• Clicking the view errors link, a heartbeat error is shown: Heartbeating between NSX management node and host ########-####-####-####-############ is down.
• Under Compute Managers, the Connection Status is Down: Compute Manager ######## cannot be connected, as its thumbprint does not match. Please edit compute manager details if thumbprint is changed.

Environment

VMware NSX-T Data Center
VMware NSX

Cause

This problem occurs because the thumbprint of the certificate that NSX Manager holds is different from the updated thumbprint following the replacement of the vCenter Server certificate.

Resolution

• Restore the Compute Manager connection as instructed in the article dedicated to that condition: After vCenter Server certificate is replaced, compute manager connection is "Down" on NSX UI
• Retry the installation of NSX on the ESXi host by clicking the Resolve button (click the error, then Resolve).
