VMware Lab Platform Troubleshooting Connectivity Issue

Products

• VMWare Hands-on Labs

Issue/Introduction

Symptoms:

• Users can't get a console.
• Users are getting an error message Console Unavailable or Connectivity Issue.
• There's a sad red face icon in the console.
• Unable to connect to the lab environment.

Cause

The sad red face happens when trying to make the initial connection to the cloud console proxy.
A sad red face is probably unrelated to the compatibility test results.
The idea of this article is to guide what to do in case you experience this issue when starting a lab in the VMware Lab Platform.
When we have seen this in the past, it has been related to a client-side firewall doing a deeper inspection of the traffic. Some firewalls might block any traffic that looks like a remote display protocol due to security concerns.

Resolution

• Disconnect from any corporate VPN.
• Try disabling the firewall from your computer.
• If you are in an office, you can try to utilize a guest network when taking the lab; they often have more ports open that might allow the traffic.
• If that doesn't work, please create a support request with VLP.

Workaround:
Connect to VLP from a personal computer or any other device non-corporate related.
Any device with a browser, internet connection, and no firewall.

Additional Information

Impact/Risks:
High, the users won't be able to connect to their labs.
