Using Google Calendar in Codeigniter 3 - php

Question

I am following this link https://github.com/omerkamcili/ci_google_calendar_api
for integrating google calendar in Codeigniter. I have
got all the credentials. But when i run this application
it returned me to http://hostname/auth/login every time
it logins to the application. When i debug it the token is not generated.

If you are encountering problems when resolving particular names, and want to verify whether the problem is with Google Public DNS, please try resolve the domain first at: https://dns.google.com. If the result does not pinpoint the problem, you can run the following diagnostic procedure. Check this documentation for more details.
