My Hugging Face Space keep starting

Uh, I didn’t do anything and it suddenly worked. The only thing I did worth mentioning is: Originally, I ran this in the local command line:

curl -Ik https://sakizuki-danboorusearch.hf.space/

The system returned:

HTTP/1.1 405 Method Not Allowed

So, I added this to the code:

    @app.head('/')
    async def head_root():
        return PlainTextResponse("")

Running this command again, the system returned:

HTTP/1.1 200 OK

I don’t know if it’s because my modification was effective, or if it was just normal HF Space network fluctuation.
