Recently somehow my HA instance banned one of the HA companion app phones due to invalid login X amount of times (it was a local LAN address). No idea how that happened but I had to go into the ip_bans yaml file and remove the ip manually. Then I thought OK, I can do “reload yaml” instead of rebooting HA entirely, but that did not work. In the end I had to reboot HA completely for it to pick up the change in the yaml file.
It would be a quality of life improvement if we had a dashboard/page for all security related topics such as banned IPs (and a removal/addition option).
