WampServer

When I access the localhost and select a project, it redirects me to a page that says "Unable to access this website, it was not possible to find the IP address of the site1 server". It is assumed that when I select a project the index.php should be opened by default, but it should not.
Does anyone know how to fix it?
Here I leave a part of my httpd.conf related to this problem:

#DirectoryIndex: sets the file that Apache will serve if a directory
#is requested.
#
<IfModule dir_module>
DirectoryIndex index.php index.php3 index.html index.htm
</IfModule>

Hi,

> It is assumed that when I select a project the index.php should be opened by default, but it should not.
NO. It is assumed that when selecting a domain name, i.e. a VirtualHost, the index.php file must be opened by default.
By choosing to "launch" a folder (this is what you do when launching a project) there is no domain name or VirtualHost, so the DirectoryIndex directive cannot be applied.

I repeat the end of the answer of RiggsFolly:
See The need for Virtual Host and Wampserver 3 - Create or add a VirtualHost
