Installation problems german language Sketchup 2021

Hi everybody, perhaps somebody is able to help me.
Since version 2021 I have problems with the installation of SketchupPro when I choose to install the german language. The installation process stops because Sketchup isn’t able to download the file:
When I choose the offline installation of SketchUpPro (with all the language files included) everything works fine.
Does somebody has the same problem with the online installation of SketchupPro?
Does somebody has a solution for the problem?

maybe the link is broken, check this article:
