You can close. The problem solved itself.
It seems to me that the problem was on the google side, and the reason was that the site is new.
Maybe I'm panicking. But it seems to me that someone is wrong with my links.
I carried out the test.
I found my website on the internet, choosing a few words especially.
It is a big relief for me that I have found myself here.
However, the link as you can see on the screen directs me to the main page. And not for a specific article.
What could be the reason?
