App mis-behaving without DNS mapping

[choxx]

The deployed app on staging (with http://domain.com:port) is not letting the user login. It stuck on the redirect loop.
While the same app if mapped to a domain (direct pointing or via proxy_pass) works fine.

Steps to reproduce:

• Clone the repo
• Create a .env file (copied from sample.env) and configure all the variables.
• Hit docker-compose up -d
• Try accessing the app on hosted on the selected port; it will let you signup with the user but wouldn't let you log in post signup.

Ping me (@choxx) for the deployed app credentials.
