Can not access the new created site

After I created a new site on my Multiuser WordPress site I do not see that site. Maybe here is someone who had the same problem or knows a solution. That would be great beacause I have no idea anymore.

So I create a new site:
Create New Site

Then click on visit dashboard:
click visit dashboard

And I see nothing 🙁
Nothing
