Hi, Ruchi. I'm not so sure you should be using the HTTPS, server configuration. What is certain that you won't be able to do so using the domain
kobotoolbox.org, because it's ours and we're the only ones with valid SSL certificates for it. Stick to the local configuration if you're not going to have your own publicly-accessible domain and your own SSL certificates. BTW, your parsing errors are likely due to uncommenting out one of the comments (as opposed to the YML-valid content of the `extra_hosts` directive).
