Sites does not appear in search

[preuley30]

Hi together.

I've set up a SharePoint intranet like this:

• Communication site (Hubsite)
  • team site
  • team site

So my problem is now, that the team sites are not appearing when I'm searching for them.

What I did before for troubleshooting the problem:

1. Checked if the site is searchable in "Search and offline availability > Allow this site to appear in search results? > Yes/No"
2. Checked the permissions for the site (Groups are inheriting the permissions from parent)
   1. Owners > Full Control
   2. Visitors > Read
   3. Members > Edit 
3. Reindex site
4. Put in the site URLs in "authoritative websites" in the SharePoint admin center > Search

I really don't know what I can check or doing for next steps to bring the sites up on the search.

Thanks.
