"Login attempt or request with invalid authentication" from Android client

I keep getting these warnings in my log, from my Android phone. Both the companion app and HA are at the latest revision levels.

2025-01-18 11:50:21.269 WARNING (MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from xxx.xxx.com (10.10.10.61). Requested URL: '/api/states/light.bedside_lamps'. (Home Assistant/2025.1.2-14946 (Android 14; KB2005))

This is originating from a widget on the phone that displays the bedside_lamps entity and allows me to turn them on or off. The widget works, so I am unclear why this warning appears.

Any ideas how to resolve this?
