Configuring webcam causes internal bad login notifications

Configuration
1

Hi, when i configure my printer cam like this:

camera:
  - platform: mjpeg
    name: OctoCam
    still_image_url: http://octopi.local:8080/?action=snapshot
    mjpeg_url: http://octopi.local:8080/?action=stream

it works fine, except for the fact that i get seemingly random internal bad login attempts from whatever device i open homeassistant on, like this:

Login attempt or request with invalid authentication from dawn-desktop-3.home (192.168.1.43). (Mozilla/5.0... )

I do not use ssl at all and homeassistant is not exposed to the net. There is no old base_url configured, but internal_url is set like this:

internal_url: "http://192.168.1.37:8123"

Any idea how to prevent this?
