With Oauth2 Google Extension for Geoserver, GeoServer home page does not redirect to Google Login page

I have installed the OAuth2 Extensions for Geoserver successfully and I was able to create the Authentication Filter and added Google_Oauth2 to the filter chains web rest gwc default

I have also created the truststore and added it to the JAVA_OPTS Path as as ../cacerts.cks

All the steps I have followed are as in the official docs

Now, when I navigate to the Geoserver Home Page as directed by the Docs, I'm not getting the Google Login Page as supposed to.

One of the issues I have discovered is after adding the Google-Oauth2 to the filter chains, when I logout as Geoserver admin, the Google-Oauth is again removed from the selected chains.

What I'd like to know is how to do a step wise check to determine the root cause of this problem. Any help will be appreciated.
