ScepterModel ComfyUI node's downloads not functioning

[o-l-l-i]

None of the ScepterModel ComfyUI node's downloads seem to work for me:

ModelNode
Failed to fetch hf://stabilityai/stable-diffusion-xl-base-1.0@sd_xl_base_1.0.safetensors to None

I am logged in to HuggingFace, and the token is ok, in case that would matter (like with Flux downloads.)

Here is the full error in console. I'm running this on Windows.
