Yahoo is rolling in a new interface and most likely, you've got that new interface. Currently, I don't have any accounts with the updated interface to fix the problem so you can either:
1) Edit your account in POP Peeper and change the "server type" from "Yahoo" to IMAP; after you do this, you should also press the "OAuth2" button and follow the instructions. IMAP is recommended over Webmail access, so this should be considered the recommended and permanent solution.

or
2) Edit your Yahoo account and switch to the Classic interface, which should be available under Settings

That worked. Thanks.
