Why the middleware BasicAuth keeps repeating verification frequently

Hi all, after logging into the dashboard page, although I did nothing, the blue status bar at the top of the page kept refreshing, then from traefik.log, it seems that the middleware BasicAuth was keep doing the verification frequently, it's that ok?

And I found that this only happens at dashboard main page, switch to the other page such as "HTTP Services", the verification will stop repeating the verification, only happen when I click on something.
