Hello Hari,
To rule out issues with the client library or your *ads.properties* file,
could you issue the access token request via curl as follows?
curl --data "grant_type=refresh_token" \
--data "refresh_token=*YOUR_REFRESH_TOKEN*" \
--data "client_id=*YOUR_CLIENT_ID*" \
--data "client_secret=*YOUR_CLIENT_SECRET*" \
https://www.googleapis.com/oauth2/v4/token
You won't be using curl to get access tokens from your app, but this will
tell us if the refresh token, client ID, and client secret you're using are
valid.
Thanks,
Bharani, AdWords API Team
