Node error "HPC Node Manager Service Unreachable"

  • Article

This article provides a solution for an issue where the HPC Management console shows the "HPC Node Manager Service Unreachable" error.

Symptoms

A compute node's health is in an error state, and the node connectivity shows the "HPC Node Manager Service Unreachable" error in the HPC management console.

The HPC service log shows the following error:

Can not find cert with thumbprint <thumbprint-id> in store My, LocalMachine.

Cause

This issue occurs if the certificates installed on the head node and compute node aren't matched.

Resolution

To resolve the issue, verify that the certificate on the head node and compute node meet the requirements. Then, import the certificate from the head node to the compute node. You can find the certificate with public key from the HPC file share on head node \\<headnode>\REMINST\Certificates.

Alternatively, you may generate a new self-signed certificate, then rotate the certificate in the cluster. For more information, see Rotate HPC Pack Node communication certificates.
