Hi @diana.gerasimova.designer , welcome to the Atlassian Community and thanks for your post.

Apologies but I don't manage to translate the text from the image. I believe the error is that the name of the site you are trying to create is already claimed / in use by someone else. Can you try please to add some hyphens like this -

diana-gerasimova-designer

to see if you can create a site with that name?

I hope this helps you.

Best wishes
