I can't connect my email to Gmail

I can't connect my email to Gmail

Hi when trying to connect Zoho with Gmail to receive a copy of the emails in Gmail I get the following error:

The server has denied POP3 access to this username and password.

The data that I am giving are:

email: email
user: email
Passw: XX
POP Server: probe with poppro.zoho.com and pop.zoho.com
Port: 995

Can you help me to know how the configuration is, thanks.
