vCenter integration is not working even when the added Cloud Proxy is online.

Products

• VMware Aria Suite

Issue/Introduction

You have recently deployed a new Cloud Proxy in Aria Operations and it appears to be online.

However, when clicked on "validate connection" in vCenter Integration it times out after few seconds with ERROR: 

Wait for response of task 'Test connection' is timed out for collector <cloudproxy_name>

Environment

Aria Operations 8.x

Cause

Communication issue between vCenter server and Cloud Proxy appliance.

Resolution

SSH into the cloud proxy VM with root credentials and check connectivity with vCenter server using below command.

1. Check if we are able to resolve the vCenter_server_FQDN from the associated DNS server:
   

   nslookup <vcenter_server_FQDN>

2. Check if we are able to connect via telnet over port 443:
   

   curl -v telnet://<vcenter_server_FQDN>:443

In most cases one of the above two will fail:

• If the connection over port 443 will fail, please contact your internal network admin to open firewall rule for port 443 from Cloud Proxy node to vCenter server.
• If the nslookup fails, check for PTR records are present for the vCenter server on the associated DNS server.
