That site does not seem to be accessible or no longer has the Jetpack plugin installed.

That site does not seem to be accessible or no longer has the Jetpack plugin installed.

Is displayed and the website cannot be added.

As a hypothesis, I added "/ wp" to the subdirectory and operated it, but I wrote it in .htaccess and moved to the main domain.

I think this is because the file itself is still in "/ wp" and the jetpack file there cannot be recognized.

Is there a way to solve it? Thank you.

Start by reproducing the add-site flow against a WordPress installation in the /wp subdirectory, then inspect how the .htaccess redirect to the main domain affects Jetpack recognition. The issue is resolved when the website can be added without the accessibility or missing-plugin message.
