You get that message because the driver is not installed properly. You have to check if you can communicate with phone via ADB/fastboot. In Windows go to device manager and check if you have Android bootloader interface driver.
Hey ty for reply.
I can see ABID in device manager but cant use the phone in adb.

Looks good but I have to ask stupid questions.
Do you put phone in fastboot mode?
Have you bind your phone to your Mi account?
Do you login on your account in both phone and Mi unlock tool?
Try to install latest mi flash tool as it will install xiaomi driver for you.
When you plug phone to computer look for authorization access both on phone and computer.
When you plug phone to your computer can you brows phone storage?
Try different USB port or different USB cables.
Keep trying you will succeed.
Some antivirus software might block Xiaomi software.

No need everything seems to be right.
Did you eventually relocked your bootloader by reflashing firmware? Have you tried "fastboot oem device-info" in fastboot mode to check lock status?
I am almost out of ideas what could be wrong. I do remember the same error I had when I disabled the windows driver while Mi unlock tool checking device. It always displayed " already unlocked" no need to unlock it again. :)
Best luck!

1.Login to your Mi account on both PC and phone and associate your phone to Your Mi account
2.Boot to fastboot mode.
3. Connect phone to PC wit original USB cable
4. Start mi unlock tool and login
If Mi unlock tool doesn't verify the phone
Check windows driver otherwise check if you're firmware is original.
post some errors description.
