If you are having trouble running Virtual Surveyor on your device, it is likely that the security of your company is blocking the connection to our online licensing and/or authentication system. You will need to ask your IT department to set permissions for the Virtual Surveyor desktop app to connect to our online systems. 

Note: Please first contact your IT support team if you are not sure about which settings you need to apply. Or contact us if you are still having problems connecting.



  • When you can authenticate yourself (sign in) but the connection to the licensing system fails, you get a message as shown below:

    Virtual Surveyor cannot connect to the licensing service

  • When you can't sign in, the connection to the authentication system fails and you will see a message as shown below:


In order to solve these issues, you need to whitelist the following URLs in your company's firewall or proxy server:

  • *.virtual-surveyor.com
  • virtualsurveyorauth.b2clogin.com

Important: Make sure to include the * in the first URL. This configuration is required for all versions of the software, including the trial version and free Valley version.

Proxy Settings

The proxy settings on your computer are automatically detected by the desktop app. Nonetheless, you can still manually configure the detailed settings through our proxy utility. 

  1. Go to File>Settings>Proxy.


Http Proxy Settings

Virtual Surveyor uses the system settings by default. If you use an http proxy, be sure to fill in all fields. Please note however, you'll need to leave the Username and Password fields empty when:

  • no credentials are required by the proxy, or
  • the proxy requires the Windows credentials of the user.
