[Defender] Defender Administrator Lockouts


I recently started getting Administrator Lockouts (my own main Administrator Account) for this site (it has recently been moved to a new hosting service) so I turned off IP lockouts altogether and cleared the log, however, I am still getting the same lockouts - it has happened 3 times already today.

When I did have IP Lockouts activated, I also Whitelisted my IP address but this doesn't seem to have worked. I don't want to deactivate the plugin altogether but it seems I may have to.

Any help is appreciated.

Kind Regards, Kevin
