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.
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”.
Find the httpd-xamp.conf file. (located in : c:xamp\apache\conf\extra)
Comment the line : Require local (eg: # Require local).
Restart XAMPP server.
Thats all. Hope this helps you. – Cody
