Unsolved qt-installer-noninteractive do not work without proxy

[user2301]

When I try to run qt-installer-noninteractive.qs in windows server 2016 without proxy, it will not work. It gets stuck at license information page. I enabled cntlm proxy but it will pop up a window and I have to enter username and password. When I cancel the dialog, I was still able to continue the installation. Without proxy it will not work but when I enable cntlm proxy and cancel the dialog without entering the username and password it works. I dont want to see the popup dialog. How can I suppress that in the script?. I dont want user to interfere with entering credentials or to cancel the dialog. The same script when i tried to run in docker also did not work. It will show network error:

[1988] Warning: QWinTaskbarButton: qIID_ITaskbarList4 was not created: 0x80040154, REGDB_E_CLASSNOTREG.
