Troubleshooting No Data Shown in the Application

This article describes troubleshooting steps you can take in situations where you have access to the application, but content is not shown.

Incomplete Display ⫘

Step One: Find the Error Type ⫘

1. Open your web developer window: right-click in the browser, and select Inspect.
2. Open the Console tab to see if there are error messages in red.
3. Check the Network tab and inspect HTTP requests that are in red. Check their HTTP status code:

• 405 METHOD NOT ALLOWED

  • This happens when some HTTP methods are being filtered by a browser extension, or a proxy/firewall configuration.
  • Solution: Make sure that all traffic coming from 216.9.204.0/22 is allowed for all methods. Network equipment such as a Cisco Content Security Management Appliance can filter non GET/POST requests.

• 500/503 INTERNAL SERVER ERROR

  • The problem is on our end. Try again in a minute. If it doesn't work still, contact support.

• 3xx/4xx numbered errors

  • The error might be on your network. Go to step two to investigate further.
  • Try opening Secureworks® Taegis™ VDR on a different, non-enterprise network.

Step Two: Check for Alternatives ⫘

1. Try the application in another browser.
   • If it works, the problem is in the browser you are using. Investigate used configuration/plugins.
   • If it doesn't work, the problem is in the network or on VDR’s side. Go for next check.
2. Try the application in a different network. Access the application from a mobile phone or a non-enterprise network.
   • If it works, the problem is a network element such as a proxy/firewall/load-balancer. You will need to make sure VDR is safelisted.
   • If it doesn't work, the problem is on our side. Contact support.
