Products

• VMware Aria Suite

Issue/Introduction

• Attempting to install the Telegraf agent on Windows VM through Aria Operations fails with the error message:  "Failed to Connect to vCenter"
  

Environment

Aria Operations 8.X

Cause

• Due to port 443 being closed, vCenter is unable to establish communication with the Cloud Proxy and Aria Operations nodes.

Resolution

• Validate if vCenter communicates on Port 443 with Cloud Proxy and Aria Operation nodes by running below commands from vCenter SSH: 
  
  curl -k -v telnet://<Cloud Proxy FQDN>:443
curl -k -v telnet://<Aria Operations Node FQDN>:443    
  
  
• If connection fails, work with your network team to open Port 443. Ensure bidirectional communication on port 443 between vCenter, Cloud Proxy and Aria Operations Nodes.
