What Should I Do When a Website Scan Fails with a Message Displayed Indicating Connection Timeout?

The possible causes and solutions are as follows:

  1. Your website is unstable. Open the website and check whether the connection is normal. Try scanning again.
  2. Your website cannot be accessed from the Internet.
  3. A firewall or another security policy has been configured for your website. As a result, the IP addresses of VSS (49.4.54.27, 49.4.8.50, 114.116.12.185, 114.115.159.33, 114.116.50.141, 114.116.50.142, 114.116.91.55, 114.115.175.79, 117.78.49.197, 117.78.49.29, 114.115.215.94, 114.115.211.231, 114.115.168.226, 114.115.129.201, 117.78.41.118, 117.78.41.126, 117.78.46.77, and 43.254.3.176) are mistakenly intercepted. Whitelist these IP addresses.
    NOTE:

    If your website cannot be accessed, check whether it is working properly. If you have any questions, feel free to send your problem on the VSS console.
