Hey @oleg, Are you using the most recent refresh\_token each time? In your second request 1 min later, you are using the exact same refresh\_token as in your first request. Each time you refresh, a new refresh token is returned and the prior one becomes invalid. Thanks, Tommy ---

I see, can I provide you c# code to check my request? ---

Hey @oleg, Sure, make sure you also have a database that updates the refresh and access tokens each time you refresh. Thanks, Tommy ---
