I didn't have time to see which backlinks are gone when it's at 27.

Probably one of the high authority sites with site-wide backlinks is sometimes unreachable for Ahrefs crawlers, could be that links really aren't present, maybe a rotating script, or due to server issues/downtime of the site with the backlinks.

Still I wouldn't worry if it goes back to 44
