uvicorn: Gunicorn with UvicornWorker is not respecting the timeout

I am setting up a timeout check so I made and endpoint:

@app.get("/tc", status_code=200)
def timeout_check():
    time.sleep(500)
    return "NOT OK"

I am using the docker image tiangolo/uvicorn-gunicorn-fastapi:python3.7 and my command to run the server:

CMD ["gunicorn","--log-level","debug","--keep-alive","15", "--reload", "-b", "0.0.0.0:8080", "--timeout", "15", "--worker-class=uvicorn.workers.UvicornH11Worker", "--workers=10", "myapp.main:app"]

I am expecting the endpoint to fail after 15 seconds, but it doesn’t. Seems like the timeout is not respected.

Is there any mistake in my configuration?
