I'm trying to update my Qt installation using online installer. It was working fine before. Now, after clearing my local cache, I can't use proxy which requires user/password. Initially, it asks for a password, and then it just shows a error message that authentication is required.
P.S. I don't know installer "version" and I suspect that it's not QTIF bug, but I don't know where I should create this report instead.
