How to make Wireless AP accessible (local server) without internet connection?

Question

Using hostapd and dhcpd, I was able to turn my raspberry Pi into a hotspot/router. It works fine, but I want to know how to make it accessible (via wifi) when it's disconnected from the internet. I have a webserver serving local apps. I want to wireless access locally running apps being served that don't require internet connection. If I try to connect to the router from any computer or smartphone while it's offline, I'll get the "No Internet Connection" and it won't resolve.

Using the create_ap tool features you can create an AP without Internet connection to share your files:

Install create_ap:

git clone https://github.com/oblique/create_ap
cd create_ap
make install

AP without Internet sharing:

create_ap -n wlan0 MyAccessPoint MyPassPhrase

You can transfert your file from the remote server through ssh using an android app.

The server should be connected to a wifi AP without Internet connexion ( router ....)

The Android device should be connected to the AP ( created through the create_ap command)

On your rpi install and configure the ssh server

apt install openssh-server

Open the sshd_config

nano  /etc/ssh/sshd_config

Add / verify the following

AllowUsers Your_username_here
PermitRootLogin no
Port 22

Restart the service:

systemctl restart sshd

Install an android application e,g: JuiceSSH - SSH Client.... to access your server.
