Can't Launch CloudCTF - Player¶
If you have not already done so, please see the article titled How to Login to the Cyber Range. If you are experiencing issues logging into the Cyber Range, please see the article titled Can't Login to the Cyber Range Exercise Area Account.
CloudCTF Troubleshooting Steps¶
Launching a CloudCTF environment is the same as launching any other Cyber Range Virtual Machine. Please navigate to the course which contains the CTF environment, and attempt to launch it. If you encounter any errors, please read through the troubleshooting steps below. For more information on launching your CloudCTF environment, please see the section titled Launching Your CloudCTF Environment.
1. Different Browser¶
Try logging into the range using a different browser. Various browsers (and even browser versions) vary in their level of HTML5 compliance, which the Virginia Cyber Range requires. We have had the best luck with the Google Chrome and Mozilla Firefox browsers, as they are generally the most HTML5 compliant.
2. Not Blocking Pop-ups¶
Please check that your browser is not blocking pop-up windows when attempting to login to the Cyber Range. Please refer to the links below to learn about allowing pop-ups in both Google Chrome and Mozilla Firefox.
Google Chrome: Block or allow pop-ups in Chrome
Mozilla Firefox: Pop-up blocker settings, exceptions and troubleshooting
4. Check Your Privacy Extensions/Add-ons¶
Please check that your privacy extensions and add-ons are not interfering with the Cyber Range. You can refer to the links below to learn how to manage or disable add-ons.
5. Check Your Computer Date and Time¶
If the user's laptop or PC dates & times are off by more than a few minutes, then Oauth authentication to the CTF may not succeed. Be sure the user machine is either to-the-minute accurate, or synchronized against your network's NTP (time sync) service. Talk to your network administrator for more information, as Root or Administrator level laptop/PC access may be required to fix this issue.
