Hi Minh, Could you post or attach the full configuration file, ensuring you anonymize any personal information? As this wil help us to look into this further.
In the meantime, if you could enclose the API request in a try-catch block and clear the cache on error. See below for example cache clearing: Authtoken.Cache.Clear(); (user.Config as AdwordsAppConfig).Authtoken = null; // obtain a new service object again and retry the call This should generate a new authtoken using your existing email and password.
