ATT.Net POP3 Server Log-In Issue

I just migrated my email from Thunderbird to eM Client earlier today. My base email server is While I have the SMTP working properly to send emails I cannot log in to the POP3 inbound server to download incoming emails. I have double checked my eM Client settings at the site below and am using for the server address and Port 995 as recommended. (!/email-support/KM1010523?gsi=8eprto)
I set up a new security key as recommended by which I am using as the password.

But it won’t log in. Below is the diagnostic log from startup.  Any help would be appreciated.

8:50:41 PM [POP3]  MailClient.Accounts.SocketException: Connection failed due to the following reason:

This error is stating that the server didn’t respond so please check with the server support what might be the fix. You can also try the IMAP settings to see if it’s working and if your credentials are correct.
