Files for Learning resource blocked

I have recently been going through the Unreal Academy and working my way through exploring blueprints course.

I am now on the last section which is titled “Blueprints for Enterprise” unfortunately though I cannot access the associated files.

As when I try to access the link provided in the more information section I get this warning and cannot connect to the site.

I don’t know if there is at all another place I can get these files but am very frustrated as I was hoping to work through these learning resources in my time off.

Does anyone know if this is an error or not and if I can get these files some where else?
