ID verification issue

My iPhone have several email addresses, and all of them worked perfectly until a few months ago. Suddenly, one of my email addresses, "****@takadaco.com" disappeared from my iPhone. The rest of the email address are working well. I deleted the email address "****@takadaco.com" from my iPhone in an attempt to re-add the email address to see if it worked. After a number of attempts, I get a screen saying that I have a verification issue. I need an advice to get the email address back to my iPhone. The email address works fine on my laptop computer.
