Unable to Install Qt

[Aamir]

I'm trying to install Qt6 using Online installer but unable to do so. I searched the Internet for different solution, but so far I've not find anything helpful.

When I use the default mirror to install Qt, I get the following error (Probably that particular server is down):

Why I change to a different mirror use the below command, I get "Cannot retrieve remote tree."

.\qt-unified-windows-x64-4.5.1-online.exe --mirror https://mirrors.ocf.berkeley.edu/qt/online/qtsdkrepository/windows_x86/root/qt/Updates.xml

What can I do to resolve this issue?
My other question is, why an offline installer is not provided for Qt6? An offline installer will be very helpful for slow Internet connections.

https://wiki.qt.io/Online_Installer_4.x#Selecting_a_mirror_for_opensource says, "don't use the full path but use the path before '/online' (no forward slash at the end)"

So your mirror URL should be https://mirrors.ocf.berkeley.edu/qt

My other question is, why an offline installer is not provided for Qt6? An offline installer will be very helpful for slow Internet connections.
