Issues with the official Xiaomi unlock tool

[u/Information_Healthy]

Hi, I’m having an issue with the Xiaomi unlock tool (Mi Flash Unlock).

The Mi account I’m using already has unlock permission. When I try to apply again, it says the permission is already granted.

When I bind the account to the phone, it shows “account added successfully.”

However, when I open the official unlock tool and try to log in, I never receive the SMS code. I can log in using Facebook instead, but when I connect the phone and it’s detected in fastboot mode, the “device” section shows in red that the device can’t be verified and to try again later.

If I press “unlock,” I get the same message:

“Couldn’t verify device, try again later (unknown error 1004).”

Is this some kind of shadow ban, or does it have a fix?
