Hi, Could you confirm if you are using the latest .Net client library <https://github.com/googleads/googleads-dotnet-lib>? Could you try to generate again an OAuth2 credentials by following this guide <https://developers.google.com/adwords/api/docs/guides/authentication#generate_oauth2_credentials>? Then, try making request again. If the issue persist, could you provide the complete logs so I could further investigate?
Also, I would suggest to use Google Chrome using incognito mode to make sure that you are using the same email address in the whole process.
