Trouble setting up Zoho mail in Apple Mail

I've followed the step by step instructions to set up my zoho email in Apple Mail and I cannot get it to connect. When I set up the mail account, it tried to connect then comes up with IMAP login failed. Verify that username and password are correct. I don't have any problem with my username or password login into my email on mail.zoho.com.

Can anyone help me out?
