Troubleshooting Steps


 Following this procedure helped to fix the issue: increase the timeout value:

    1. Make a backup of the K2HostServer.exe.config (see for its location)
    2. Edit the config
    3. Add the following under
      <add key="Sourcecode.SmartObjects.Services.PDFConverter.NavigationTimeout" value="300" />
