If Kerberos Authentication is used in Qlik Sense then the following error can be observed: Error: QVX_UNEXPECTED_END_OF_DATA: HTTP protocol error 401 (Unauthorized). Currently, Kerberos Authentication is not supported. This is currently under investigation by R&D for future enhancement. The only workaround is not to use Kerberos Authentication.
In addition, the License and Operation Monitoring Apps will not reload anymore if using Kerberos. When trying to Reload them, the following error is observed:
Error: QVX_UNEXPECTED_END_OF_DATA: HTTP protocol error 401 (Unauthorized):
'Negotiate' authentication schema provided by the web-service is not supported or your credentials are not valid.
Qlik Sense: June 2017 and newer

The article "Monitoring Apps Troubleshooting Tool
" provides details on how to switch the Monitoring Apps to use Certificates for authentication, ultimately bypassing the Kerberos restriction.
