VCF Operations Cloud Proxy Offline

Products

• VCF Operations

Issue/Introduction

• Cloud Proxy is reporting as 'Offline' in the Cloud Proxies menu.
• The same cloud proxy reports its Health Status in the VCP Operations Admin UI as 'Outdated life status'
• The console for the Cloud Proxy in vCenter, as the error below;

  • [FAILED] Failed to start HAProxy Load Balancer.

Environment

VCF Operations 9.x

Cause

When haproxy starts, it attempts DNS resolution for the FQDNs listed in /etc/haproxy/haproxy.cfg.

FQDNs which do not exist in the DNS records lead to recursive queries being sent to the upstream DNS server, causing a timeout. This led to the haproxy startup process failing.

Resolution

Please follow the resolution outlined in the KB below;

• The firstboot of the VCF Operations Collector fails because HA Proxy does not start and times out
