Clean installation - Login attempt or request with invalid authentication message

Just did clean installation on Raspberry Pi 4 and receive following message from HA:

Logger: homeassistant.components.http.ban
Source: components/http/ban.py:82
Integration: HTTP (documentation, issues)
First occurred: 18:14:34 (2 occurrences)
Last logged: 18:14:34

Login attempt or request with invalid authentication from 192.168.2.4 (192.168.2.4). Requested URL: ‘/auth/token’. (HomeAssistant-Extensions-PushProvider/2022.8 (io.robbie.HomeAssistant.PushProvider; build:2022.387; iOS 16.0.2) Alamofire/5.4.4)

What can be causing this? (see full log below)

Edit 02-10-22: Some binding had been defined in router and after deleting this, message has not appeared anymore

could you elaborate on the binding you’d configured? I’ve got a unifi UDM-pro setup and couldn’t find anything along those lines. However I also get the same error message…
