VCF Instance Cloud Proxy Registration validation failed

• The SDDC Manager log /var/log/vmware/vcf/domainmanager/domainmanager.log contains an entry - 

YYYY-MM-DDThh:mm:ss.sss+0000 DEBUG [vcf_dm,xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx,xxxx] [c.v.e.s.c.v.util.ResponseUtil,dm-exec-xxx]  Build validation response: {"errorCode":"BROWNFIELD_VCF_INSTANCE_CLOUD_  
PROXY_REGISTRATION_VALIDATION.error","arguments":[],"context":{"severity":"ERROR","bundleName":"com.vmware.evo.sddc.common.validation.errors.messages","validation.taskId":"xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"},"message":"VCF Instance Cloud Proxy Registration validation failed","remediationMessage":"Verify VCF Instance Cloud Proxy Registration is properly configured"}

Environment

VCF 9.1.0.0

Cause

• The SDDC Manager first logs into the primary VCF Operations analytics cluster
• It then retrieves the inventory, after which it discovers the registered Cloud Proxy and attempts to validate communication with it
• VCF Operations was still assigned to the default analytics cluster Collector Group, thus the validation fails

Resolution

• To resolve the validation error being encountered -
  • Log into VCF Operations UI > Administration > Integrations page
  • Edit the VMware Cloud Foundation infrastructure account
  • Under the VCF Credentials section - there is a "Cloud Proxy / Group" drop down menu
  • Change the setting from the entry under the "Default Group" to the dedicated Cloud Proxy appliance under the "Ungrouped Collectors" list
  • Clicked Save
• Retry the previously failing workflow
• The issue is then expected to have been resolved
