The web console of the VM from VCF Automation 9.X do not load, it keeps spinning

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

Attempting to open the Open Web Console or Open Remote Console for a Virtual Machine (VM) results in a continuous spinning wheel or the URL failing to resolve.

Environment

VCF Automation 9.X

Cause

VCF Automation appliances require bidirectional communication with ESXi hosts on specific ports to manage console sessions and data transfer.

• Port 902: Required for the VCF Automation appliance to contact the ESXi host for MKS (Mouse, Keyboard, Screen) console traffic.
• Port 443: Required for management and OVA deployment tasks.

If these ports are blocked by an internal firewall, the console will fail to initialize.

Resolution

      To resolve the spinning console and connection issues, follow these steps:

1. 1. Validate connectivity from the VCF Automation appliance to the ESXi host where the VM resides using the following command: curl -vk https://####:902 (Note: Replace #### with the ESXi host IP or FQDN).
   2. If the connection fails or times out, engage internal network team to open Port 902 (TCP/UDP) bidirectionally between the VCF Automation appliance(s) and all ESXi hosts in the management and workload clusters.
   3. Ensure Port 443 is also open for OVA import and general management traffic.
   4. Once the ports are opened, refresh the VCF Automation portal and attempt to open the console again.
