Android email does not accept password generated from Two Factor Authentication

Hello,
we are using Zoho mail on Android phone. We have generated password from Two Factor Authentication. Suddenly it has stopped working: "could not connect". We have revoked the old one password and generated the new one, but we cant log in to our e-mail account on mobile : "Username or password incorrect"

Any suggestions?

Thank you,
Arunas
