   Try to load this page with any browser: *http\://*[***YourLicenseServer***](#user-content-fn-1)[^1]*:2468/web*\
   \
   Start the server if it is not running <br>
2. Make sure that the correct license server is set in the Dock license manager:\
   For example.: '*http\://*[***YourLicenseServer***](#user-content-fn-1)[^1]***:**&#x38;731'*

   Navigate to programs and features > locate Agacad license server > Uninstall > Download and install [the latest version](https://cdn.iv.agacad.com/attachments/1078/NetworkLicenceServer-4.0.2020.2.msi)<br>
