Error unlock Bootloader

[575massimo]

hi, i'm trying to log in to unlock the bootloader (done many times and never had any problems) only that for a few days it gives me this message:

"account application area query failed. please try again later"

does anyone have a solution?
Thanks

As this post is 9 yrs old this is a shot in the dark. I am trying to unlock my redmi note 4 bootloader and have tried every sugestion on the net but I always fail to get a validation code either by text or email when I sign into mi unlock tool?
Did you ever get it sorted?

Funny thing. I have put new sim in, but have wiped data and created new mi account with new number. When I tried on other phone with old sim in, I got the validation text. Will try again
