IMAP not connecting

I have the details of error that says:

Array
(
    [0] => Can't open mailbox {poppro.zoho.com:995/pop3/ssl/}Inbox
    [1] => Not connected. No email resource at: {poppro.zoho.com:995/pop3/ssl/}Inbox
    [2] => Connection could not be closed. No POP resource.
)

(
    [0] => Can't open mailbox {poppro.zoho.com:995/imap/ssl/}Inbox
    [1] => Not connected. No email resource at: {poppro.zoho.com:995/imap/ssl/}Inbox
    [2] => Connection could not be closed. No POP resource.

Searched the forum and moderator says to disable TFA but I have TFA disabled but still cannot access imap/popup.
