Problem with Apple Mail and Zoho mail account

Problem with Apple Mail and Zoho mail account

I am no longer able to connect to my Zoho mail from Apple Mail. I get the dialog box saying "Cant connect to the account [my account]. Enter the Pasworrd for user [my username]. And asks for password. When I enter my password it returns. "Unable to verify account name or password." I did not change any settings either on my computer or on Zoho mail.  Need help.
