One account getting IMAP error

Recent the cable into my house was replaced as was the modem and router. Since then my Gmail account will not open giving me an IMAP issue. My second account from mail.com works fine. Gmail also works fine from the internet. How do I repair this issue?

Check the IMAP settings for the Gmail account in Menu > Tools > Accounts. It should be port 993 and Use SSL/TLS on special port.

If that does not work, change it to the same port and security policy that the mail.com account is using.

Thank you very much problem solved.
