Hello, I believe this error message means that the refresh token you're using isn't actually associated with AdWords. There is an alternate way to fetch refresh tokens for AdWords compared to other Google products. Since it seems you are using the .NET library, I suggest checking out the OAuth2 examples <https://github.com/googleads/googleads-dotnet-lib/tree/master/examples/AdWords/CSharp/OAuth> folder for that library, which contains code examples for various OAuth2 use cases, including fetching the refresh token.
