comcast email won't connect

This seems to happen every 6 months where my email

loses it's connection for what ever reason password? server? who know's.

The connections seem right but these are the warnings I'm getting.

My email address was purposely taken off for this image but it is back in.

It might be it won't except the password anymore but can't find how to change

the password. Haven't had email since April 7th so any help would be appreciated
