Environment

VMware NSX

Cause

• NSX Manager periodically executes "GET /api/v1/node/central-config" against NSX Edge nodes.
• If no response is received from the NSX Edge node within 30 seconds, the process times out and the subject message is logged.

Resolution

Information retrieval may occasionally fail, but this will not affect functionality.
