Question

LAMP

Hello.
Why won't the website installed on my Ubuntu computer load? I'm trying to access this site from my smartphone. The smartphone is connected via WiFI to the computer with the site. It turns out a local network.
server ip 10.42.0.1. I drive it in my smartphone and I can not load the site.
Server: Linux-Apache-MySQL-PHP
Maybe you need to write something somewhere?

Answer 1

most likely the firewall on the computer kicks off requests to port 80 + it is necessary that Apache listens not only to 127.0.0.1, but also to 10.42.0.1
