Hi, The error *Failed to refresh access token* appears when you did not refresh your access token. Could you confirm if you have followed the steps in getting your refresh token <https://developers.google.com/adwords/api/docs/guides/first-api-call#get_an_oauth2_refresh_token_and_configure_your_client>? If not, could you follow the guide and add the refresh token in your properties file?
Let me know how this goes.
