Not able to add my site to Google Search Console

I am trying to add my site using the html file upload. But each time getting same error.

Could not find your site. Please check that you provided the correct URL for your property.


In my browser my domain is resolving without any problems and wordpress is installed.

Url is startblog(dot)xyz
What am I doing wrong here?

BTW the domain folder is outside public_html. Which should be OKay? WordPress ...
