Ahref finds more referring domains than Google…

Hi,

I have an issue with one of my websites as Google says it only has 6 referring domains (RD), but Ahref says it has over 350 RD, Majestic says over 100 and Moz says 25.

Normally, or at least with all my other sites, Google alway finds the most RD. Typically 25% more than Ahref.

My property in Google Search Console is over 90 days old, and the site is over 2 years old.

Has anyone experienced anything similar?

Or does anyone know where I can find more information about the issue?…
