Cause

Network SSH Connectivity Issues: Network or SSH connectivity between the nodes or with a remote Virtual Data Center (VDC) may be unavailable.

SSH Keys Issue: Existing SSH Keys in the VDC may not have been configured correctly.

Resolution

SSH port should be open between the VDC in a federation to allow key rotation.

Contact Dell ECS and ObjectScale Technical Support with the logs of the node from which the console was run if this does not resolve issue:
