VMWare Hands-on Labs Education: On-demand Training

Here is a list of common network connectivity issues that can be seen in the Lab console.

Generally, when experiencing network issues while connecting to a Lab, it is due to several possible local network configuration settings.

Follow these steps for troubleshooting:

Check your connectivity to the labs.
1. Visit the following link associated with your Lab and perform the test:
  - VMware Hands-on Labs
  - Education OnDemand Labs
  - The latency must be below 300 ms.
  - Ensure that you have the recommended bandwidth and latency to run the application correctly.
2. If your WiFi network is overloaded, use a hard-wired Ethernet connection.
Ensure you are using the latest version of the supported browsers.
1. Clear your cache/cookies.
2. Restart the browser to reload the page.
Browsers will block content based on your browser security settings.
1. Disable all AdBlockers.
2. Use a different supported browser.
Corporate or educational networks can sometimes block required WebSockets, which are necessary for a successful connection.
1. Validate that you can access the labs through your network by attempting to access the lab from a different network.
2. Confirm that your network is not blocking content due to a firewall or a web proxy.
If you have a VPN or Proxy, try disabling the VPN/Proxy and refreshing/reloading your browser to ensure Hands-on labs is working directly through your Internet connection and not through your VPN or Proxy.
As a last resort, end your lab, re-enroll, and start again.
