Cannot download big model files

Hello guys,
I have a pretty simple problem. I cannot download model files from huggingface that are bigger than 2.6GB. I tried to download the stable diffusion 1.5 and 2.1 checkpoint file. The download stream stops at exactly 2.6 GB and discontinue. Do I need a subscription?
Tested in different browsers on two different machines in two different regions (and two different internet connections). Of course enough drive space available.
