Apple Mail error “p38-imap.mail.me.com” on the default ports timed out."

Suddenly this morning, I am getting the "Connections to the server “p38-imap.mail.me.com” on the default ports timed out." error message for my iCloud Apple Mail on both my MacBook Pro and my Mac Pro. Both are running the Big Sur 11.1. My G mail account is also showing a similar timeout message on Apple Mail but my Exchange account on Apple Mail is working normally. These are on two different ISPs and the mail still is accessible on my iPhone and iPad, both with the latest operating systems as well as through the iCloud website.
