Cant connect my Zoho Email to Apollo.io account

Cant connect my Zoho Email to Apollo.io account

Im trying to add my Zoho email to my Apollo account in order to be able to send emails through Apollo but I keep getting time out error.

In order to set the email account there is a small form in Apollo I have to fill.
For email and password I use the same one I use to login into Zoho mail.
Then there are the fields for IMAP Host and Port, and SMTP Host and Port.

IMAP Host: imap.zoho.com Port: 993
SMTP Host: smtp.zoho.com Port: 465

I also tried in SMTP to use port 587.
But I keep getting this error:
Your request has timed out or is invalid (Error Code 04112). Please try again.

If I use imappro.zoho.com I get the error:
Host provided is not an IMAP server

Both SMTP and IMAP access are checked on the Zoho account configuration.

I dont know what else to do, please help me.

Best regards,
Leonardo
