Configurator - Login attempt or request with invalid authentication

Hi!
I have noticed that when I click the configurator icon, I got the notification:

Login attempt or request with invalid authentication from localhost (127.0.0.1) (Python-urllib/3.8)

I can disable the message, but as soon as I click the configurator button, I get directly a new notification.
It doesn’t give directly problem, since I can use configuration embedded in HA. So it is more of an annoying issue.

I have read the similar thread of the issue, but can’t solve it, or maybe don’t understand how to solve it.
I have tried to add below code in configuration.yaml. Something that I read in other threads could help.

  use_x_forwarded_for: true
  trusted_proxies: 
    - 127.0.0.1

But I didn’t make any difference. So I don’t know what to do to get rid of the notification.
