When I open it, Not Found

appears.

Answer 1

Have you not configured the domain name properly?

Does your directory point to the public directory under the root directory?

In the public directory, there is an index.php file, in which the text is output echo 1;

If there is output, it means there is something wrong with the code.

There is no output, which means there is something wrong with your domain name configuration.
