Hello, good day!
This usually happens temporarily and can be caused by a variety of factors, including potential issues with your internet service provider (ISP) or if you have a VPN installed.
Can you try using InPrivate/Incognito or a different browser?
If you still can't download the ISO, let me know what language you need it in, and I'll provide you a direct link.
I look forward to your update and am willing to collaborate with you until we resolve the issue. Keep me posted by clicking "Add comment" below.
