Cannot serve the built app through an ad-hoc local network

[pc-magas]

On my computer I've setup an ad-hoc wi-fi network and I have build a meteor app with the purpose of simulating a deployment to my pc and to see how an meteor build android app will interact with the server.

Therefore I typed I run:

git clone https://github.com/meteor/todos.git
git fetch
git checkout react
git pull origin react
npm install
meteor build ~/builds/todos --server=http://10.42.0.1:8080
cd ~/builds/todos/application/server
npm install
cd ../../

Afterwards I run:

ROOT_URL="http://10.42.0.1" MONGO_URL="mongodb://localhost:27017/superdb" PORT=8080 node main.js

I also tried:

ROOT_URL="http://10.42.0.1:8080" MONGO_URL="mongodb://localhost:27017/superdb" PORT=8080 node main.js

But both when I try to visit from another device connected to ad-hoc network using curl I receive:

HTTP/1.1 302 Found
Location: https://10.42.0.1/
Access-Control-Allow-Origin: *
Date: Thu, 24 Aug 2017 11:08:50 GMT
Connection: keep-alive
Transfer-Encoding: chunked

Also when I visit through browser in the computer connected to the ad-hoc network for some reason gets redirected into https connection to default port ingoring port 8080. But on the computer that runs the server if I visit http://0.0.0.0:8080 it gets served correctly.

Also I tried theese commands to debug if there is any network error (please keep in mind that I run ubuntu linux 16.04 that also serves the ad-hoc wireless network):

On the ad-hoc serving computer I setup a netcat to listen into port 8080

nc -4 -k -l -v 10.42.0.1 8080

Then on another computer connected into the ad-hoc (rasberrypi) wi-fi I run:

nc 10.42.0.1 8080

Then whatever I typed into the promt I could see it into the ad-hoc serving machine therefore is not ad-hoc's fault or firewall closed port.

Furtermore If I run the app through meteor run command then on the rapberrypi's browser when I visit the http://10.42.0.1:3000 url it works just fine.

Do you fellows have an Idea why that happens?
