Issue/Introduction

• During the VCF 9.1 upgrade, while deploying VCF Management Services, when click "Install" - the following error is returned - 

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,#####################,####] [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":"############-####-####-####-##############"},"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

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