I just got in to an error when trying to access the Localhost (XAMPP v3.2.1) over the home network. Then i was searching what went wrong, here i found it and thought sharing the solution with you guys. By defualt XAMPP has set the security with httpd-xamp.conf file. So only have to comment / edit few lines.

Access forbidden!

New XAMPP security concept:

Access to the requested object is only available from the local network.

This setting can be configured in the file “httpd-xampp.conf”.

 Solution :

1. Find the httpd-xamp.conf file. (located in : c:xamp\apache\conf\extra)

2. Comment the line : Require local (eg: # Require local).

3. Restart XAMPP server.

   Thats all. Hope this helps you. – Cody
