 === Actual Results
 1.  **Bug Reproduction**: The issue was successfully reproduced by
 following the steps outlined by the original poster. The bug still
 persists.When a user attempts to register a site that is already taken—by
 navigating to wp-signup.php?new=sport—WordPress still displays the
 message:"The site you were looking for, https://sport.localhost:8889/,
 does not exist, but you can create it now!"This message appears at the
 bottom of the page, below the "Create Site" button, even though the site
 is already registered. This is the [https://ibb.co/NgrQ0jDh screenshot
 before the patch].

 1.  **Patch report**: The issue resolved with patch as expected. It
 doesn't display the message as mentioned above and when we try to create
 site using the above slug. It says "Sorry, the site is reserved". This is
 the [https://ibb.co/YFfMZmGm screenshot after the patch].
