Outlook stopped downloading IMAP

Since saturday my outlook stopped downloading my emails, I haven't made any changes to the configuration. The error says it cant connect to the server....or no error at all and the emails are not downloading, must see them online.

Outgoing: imappro.zoho.com
Ingoing: smtp.zoho.com
Ports: 993 and 465
