nothing is up to date in comfyui!!!

### Custom Node Testing

- [ ] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

flux-2-klein-base-9b-fp8.safetensors in comfyui base model libray cannot be found and downloaded, Starting simply with a porposed model does not even work... What else?

### Actual Behavior

flux-2-klein-base-9b-fp8.safetensors in comfyui base model libray cannot be found and downloaded, Starting simply with a porposed model does not even work... What else?

### Steps to Reproduce

Load the base model "image_flux2_text_to_image_9b" from the model manager

### Debug Logs

```powershell
Diffusion model download fails
```

### Other

_No response_

Start by reproducing the failure when loading the base model "image_flux2_text_to_image_9b" from the model manager, then trace the reported "Diffusion model download fails" message to the relevant entry point. Done means the flux-2-klein-base-9b-fp8.safetensors model can be found and downloaded and the proposed model starts successfully.
