Macbook Pro stopped loging in to iCloud and FaceTime

I have an old Macbook that has been working flawlessly for years.

For the last 2 day I cannot log in to iCloud or FaceTime. I changed my AppleID password but nothing works. The screen captures below show the errors: The first error below is when I log in to iCloud and the second is from FaceTime.

This has been working for years without any issues.

What is happening?

How Can I fix this?
