I think my AppleID has blocked one of my devices.

So, I have my appleID in many devices (An Apple Watch, iPhone, iPad, AppleTV, MacBook Pro 2012 and MacBook Pro 2016). They all have the same AppleID. it works for iCloud, Apple Music, my apps, everything.

I haven't used the MBP2012 in a while and every time and it kept asking me to log in in to my AppleID. I tried and it says 'incorrect password'. I thought I was typing something wrong. Everything's fine. The same password and email work for all my other devices. I log out and in again in every single one of them with no problem, except with the MBP2012.

I thought it could be a virus, so I did a clean OS install from scratch. Still couldn't login.

I thought maybe it was a problem about the domain being blocked or something, so I created a new AppleID, and it worked. The new one works without issues.

So, is there a chance my first Apple ID sort of blocked my MBP 2012 and refuses to login there for some reason?

Help!
