unable to sign in to facetime or messages on macbook

Hi All,

I am unable to sign in to my facetime and messages on my macbook using the same apple Id/icloud Id as my iphone.

I provide my credentials > click next > shows the cancel button and spinner > asks for credentials without showing any error message on screen.

Same outcome for both (facetime and messages). I have tried changing my password and all the steps mentioned in -> https://support.apple.com/en-us/HT204408

Even the NVRAM Step.

Any idea how to reset the apps completely (remove saved data/credentials/history)?

If more information is needed can you let me know how to provide.

Thanks.
