Linking my Zoho mail to Apollo.io

Linking my Zoho mail to Apollo.io

I'm trying to link my Zoho mail to Apollo.io and already generated the app password but still it won't log me in it says below:

An unknown error occurred connecting to the IMAP server with the provided settings. Check that the settings you entered are correct. For more information contact your hosting provider.

The error returned by the IMAP server was: "You are yet to enable IMAP for your account. Please contact your administrator (Failure)"


How to fix this?
