Thank you chrisretusn.
Setting up an App Password got things working again.
Quote:
App passwords
Some apps or services require you to enter your username and password to connect to your Aol account. If you’re not comfortable sharing your password with that service, Aol can generate an App password, a one-time password to use with just that app/service, instead of your normal password.
When do I need an app password?
Some older, less secure apps/services don't support Aol's own sign-in method and ask you to give your username and password directly to the app/service instead. In cases where you do not see the Aol sign-in box, you should generate and use an app password.

And
imap.aim.com and
smtp.aim.com still work too.
