VMware Aria Automation inaccessible with error: "This site can't be reached"

Products

• VCF Operations/Automation (formerly VMware Aria Suite)

Issue/Introduction

While trying to access the VMware Aria Automation UI from a Windows jump server, the application is inaccessible and returns the following error: "This site can't be reached".

Additionally, attempting to SSH into the VMware Aria Automation appliance using a client such as PuTTY fails with the following error: "Network error".

Environment

Aria Automation 8.X

Cause

This issue occurs when port 443 (HTTPS) and port 22 (SSH) are blocked on the Windows jump server or by a network firewall.

Resolution

To resolve this issue, validate that ports 443 and 22 are open and accessible from your Windows jump server.

1. Open PowerShell on the affected Windows jump server.
2. Run the following command to test connectivity over port 443:

   Test-NetConnection -ComputerName <Aria_Automation_URL> -Port 443
   

3. Run the following command to test connectivity over port 22:

   Test-NetConnection -ComputerName <Aria_Automation_Node> -Port 22
   

4. Review the results. If the commands fail, it indicates that the ports are actively blocked or there is a localized issue with the server itself.
5. Reboot the Windows jump server to ensure the issue is not caused by a temporary OS-level port block or local firewall hang.
6. If the connection continues to fail after the reboot, contact your internal network or security team to ensure traffic is allowed on ports 443 and 22.
