The license watermarks will be shown based on license validation in reporting components as per licensing. Bold Reports licensing requires internet connection for the license validation. So, you should ensure the firewall is not blocking the site http://websiteapi.boldbi.com/ from your network for license validation. If you don’t have the network problem, then you should ensure the license token registered, as properly with your application as explained in below documentation.
