Repeated http login attempt error messages from HA node itself

I put a password on my HA, using the secrets.yaml file. entries are:
“api_password: !secret default_password”, where default_password is defined in secrets. Manually logging in works fine, but I see the following message on repeat in the HA log:
“WARNING (MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from 192.168.1.104”, which is HA’s own IP address. I’m quite confused.

Do you have some script somewhere that tries to send data (device status) to HA via an API?
Or maybe did you install the iOS app and incorrectly configured it?

Thanks for your response.

I have installed the ios app on my phone, but it logs in and I can see everything. How would I determine that that’s the problem? The log file’s very inconclusive and vague.

I’ve also got homebridge installed. Could that be contributing?

Possibly homebridge could be the culprit, easiest way is to deactivate anything that connects to HA and activate them one by one to see which one fails / generates the errors. It’s a bit difficult from here without seeing your setup

Thanks for the advice, I’ll give that a shot and report back.
