301 not showing in any tools

About a month ago i found an expired domain on playboy and 301 redirected to my adult site. The link is do follow and it works. I click it.. i get my site. That domain name nore playboy shows up as a backlink in google or ahrefs.If i google search that domain name it shows up in the search with the meta data from my target site. Is there something i am missing here? I figure i would at least see playboy in my sites link profile since its a 301.

I am doing a wildcard 301 via virtual host file.

Thx

There may be a bug with an expired domain.

You've done everything right. I would check search console just to make sure your target page is still indexed. It will eventually show up in ahrefs as a 301. Give it a little more time. I know it sucks to wait! Also, maybe the playboy page has not been crawled recently.
