The site is not accessible by ip in the local network, how can I access it through a browser?

Question

Apache HTTP Server

Picked up a DokuWiki server today on an old computer. Works on Apache2. When I enter in the browser on the host
localhost/dokuwiki/ it shows everything fine. When I enter it ah pi instead of localhost, everything is fine too! But if I try to connect using the same IP from another computer, no connection occurs. The DokuWiki site is located in the /var/www/html/dokuwiki folder.
How to be? How to connect to the site from another device on the same local network?

Answer 1

It even does not give out the test page apache2?
Is port 80 open in the firewall for incoming? If for the test in LAN - you can disable the firewall altogether.
If ubuntu\debian - then the command sudo ufw disable

Answer 2

You can try to check the availability of the host: port in general via
sudo python3 -m http.server 80
If anything - try to open the port via iptables
sudo iptables -A INPUT -p tcp --dport 80 -j ACCEPT
