1. Install NodeJS if your machine does not have it installed.
2. Install Localtunnel.
npm install -g localtunnel
3. Start your rails app on your machine
4. Request a tunnel to your local server:
lt --port 3000
5. Copy the URL in the output:
your url is: https://cgoyfetijd.localtunnel.me
to access it from any machine.
This gave : 504 Gateway Error (with nginx server version)
Due to security, since Rails 4.2 the local server is not exposed to the network. To fix this, start the server like this :
rails s -b 0.0.0.0
When this is accessed from another machine, the log file shows the error:
Cannot render console from 22.214.171.124! Allowed networks: 127.0.0.1, ::1, 127.0.0.0/127.255.255.255
config.web_console.whiny_requests = false
does not work.
config.web_console.whitelisted_ips = '126.96.36.199'
to allow that particular IP to connect remotely to your local Rails app. To whitelist the whole private network:
config.web_console.whitelisted_ips = '188.8.131.52/16'
