Was that Space working before the last two days?
If we know which Space it is, we might be able to tell whether the error is caused by HF or by the creator’s code.
If you say “the last two days,” there’s a strong suspicion that an internal server error (the kind that doesn’t show up on the status page) has occurred.
e.g. https://huggingface.co/proxy/discuss.huggingface.co/t/my-hugging-face-space-keep-starting/174616 https://huggingface.co/proxy/discuss.huggingface.co/t/unban-me-please/174586
However, there are also many cases where the Space’s code simply stops working… (which, given that we use Python, is a constraint that’s bound to happen to some extent).
Unless we know which one it is, no one will be able to fix it.
