  1. Stop the Qlik Sense Engine Service.
  2. In the [Settings 7] section in Settings.ini, add the setting WebFileUseWinAPI=0

    [Settings 7] 

    In both Qlikview and Qlik Sense, setting the settings.ini WebFileUseWinAPI = 1 will activate the old way of handling web files which use Windows APIs instead of libcurl and lets Windows handle the proxy redirecting. Since the internet proxy is bypassed using libcurl it is useful to activate this setting if you require the web traffic to go through the proxy.

    For instructions on how to edit the settings.ini file see How to modify Qlik Sense Engine's Settings.ini.

  3. Start the Engine Service.
