Why do I get warnings about failed login on all restarts?

The error in the log says “2021-03-17 07:34:59 WARNING (MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from localhost ( (curl/7.69.1)”

But I don’t have any curl requests to my ha instance. The log has 4 of these errors on every restart.

Any ideas ?
