jan Fietje 2 model won't download & run

Describe the bug I have tried to use the Fietje 2 model (https://huggingface.co/BramVanroy/fietje-2-chat-gguf) to run, but it doesn't run. It does work in Ollama (https://ollama.com/bramvanroy/fietje-2b-chat:Q8_0) without issues. There is no clear message why it doesn't start. I have tried by adding the model directly by copy & paste the huggingface url en choose the Q8 model, but it doesn't download (stuck at 0%). So, I downloaded the GGUF manually and imported into Jan. This works, but when I try to start the model, it doesn't start, but I also don't get a clear error message.

Expected behavior I expect the model to run, just like with Ollama.
