Why does the session cookie work when serving from a domain but not when using an IP?

Question

I have a Flask application with sessions that works well on my local development machine. However, when I try to deploy it on an Amazon server, sessions do not seem to work.

Answer 1

It is possible to create session in the Chrome browser using IP.

My config file has these configurations:

    SERVER_NAME = '192.168.0.6:5000'
    SESSION_COOKIE_DOMAIN = '192.168.0.6:5000'

It allowed me to use a local virtual machine and the cookie worked perfectly on Chrome, without the need for a local FQDN.
