Huggingface downloads via nodes doesn't work

[fintarn]

Your question

Hello,

I recently did a fresh installation of comfyui portable + manager and I've noticed that huggingface downloads via custom nodes doesn't work.
I tested Kijai's segment-anything2, Kijai's (Down)Load HunyuanVideo TextEncoder, z-tipo-extension, etc.

They all give the same error, relating to 401 Unauthorized, so it's not a problem with an individual node. For example:
401 Client Error: Unauthorized for url: https://huggingface.co/KBlueLeaf/TIPO-200M-ft2/resolve/main/TIPO-200M-ft2-F16.gguf
Invalid credentials in Authorization header

huggingface-hub version in my python embeded is 0.29.2, which seems fairly new.
Available versions: 0.30.1, 0.30.0, 0.29.3, 0.29.2
I guess maybe it could be that there is somehow an invalid token set or something like that but I have no idea how to check it. I never manually set any token or anything like that.
I don't have a lot of custom nodes installed, and the entire comfy install is quite new. What could be the issue? Please help.

Disable all custom nodes except the one and try again.

In case someone else stumbles upon this error, here's what worked for me:

1. Go to your Huggingface cache folder (mine's location was specified in an environment variable called HF_HOME)
2. Open the token file with a text editor.
3. Add/replace your Huggingface access token (can be created here)

[Hangover3832]

In case the token file doesn't help and you still struggle with this, set your hugginface token in the environment variable "HF_TOKEN" before comfyui is launched.
