I set both hide wp-login and wp-admin on, set access type error to forbidden 403. wp-login gives 403, but wp-admin gives 404.
As a side note, your sever or ip block has a problem with microsoft, outlook blocks your confirmation email.
I wanted to check if there was any progress on this fix.
We're using version 1.1.1 on lots of websites and see this issue across all of them.
404's are then being cached in browsers and clients can't get into their admin dashboards.
