I can't enter Qlikview server license on a server using the proxy.
Let see the attached file for the error message.
Request a LEF-file (License Enabler File) from the QlikTech orders department (the same email that sent you your licenses).
In the management console, paste the LEF information, enter serial and control and click "apply".
This is the easist way around a proxy if you cannot get to our License Enabler Servers.
