Hi guys,
So I had this issue. I tried to refactor the OS and it gave me the error "Activation Lock status could not be determined because the activation lock server cannot be reached." I solved the error by connecting the laptop to **my iphone's internet ** and not by house wifi. My phone and my laptop used the same AppleID so I guess that removed the lock??? I am not sure but It worked!!! Good luck.
Note: Before this step, I reset the SMC.
