I know I have broken links but they aren’t detected

Using the latest version of wordpress and broken link checker (1.11.5).

I used “force recheck” after getting no results and still no results.

“Look for links in” I have “pages” and “posts” checked. “Post statuses” I have “published” checked.

“Link types” to check I have HTML links, HTML images, Embedded YouTube videos, Embedded YouTube videos (old embed code) & Smart YouTube httpv:// URLs all checked.
