Can not access Apple.ID

Hi, I have changed my Apple.ID password through my iphone which is linked to my MacBook Pro.

I am trying to add accessibility to an application but need to add in my Apple.Id password on my MAC.

It keeps giving me an error: There was an error connection to the Apple ID server.

I also can not log into apple.id.com

Is there a problem on Apple's side?

I need this programme to work on my MAC to complete my work.

Please help
