Login attempt or request with invalid authentication

**iOS device model, version and app version**

Model Name: iPhone 15 Pro
Software Version: iOS 18.1
App version: 2024.934

**Home Assistant Core Version**
2024.11.1

**Describe the bug**
Every now and then this notification pops up in Home Assistant:
>Login attempt or request with invalid authentication from localhost (127.0.0.1). See the log for details.

When checking the logs, this comes from one of my iOS devices:
>Logger: homeassistant.components.http.ban
Source: components/http/ban.py:136
integration: HTTP (documentation, issues)

>Login attempt or request with invalid authentication from localhost (127.0.0.1). Requested URL: '/api/websocket'. (Home Assistant/2024.10 (io.robbie.HomeAssistant; build:2024.934; iOS 18.1.0))

The iOS version and the TestFlight build number make it clear that it's me and not someone else trying to hack my network.

So far every time I saw the error it was pointing to `/api/websocket`
