I'm not able to help, but I have the exact same error in the DFP API client since yesterday. This leads me to believe there is an problem in the Google.Ads.Common library (home of the OAuth2 classes), or a more fundamental problem in the API service. I've tried making a new service account and regenerating certificates, but nothing helps. Please let me know if you figure out the problem.
