Hi @Jman,

This could be happening for a few different reasons. Can you see my post here and let me know if it helps?

Timeout when refreshing access tokens

Hi @bo.zhang, Thanks for reaching out about this. This can happen for a few different reasons. These are the most common: If a new access token is generated, both the previous access token and refresh token will become invalid. So you will need to update each of these tokens each time you request a new access token. Another situation that can arise is if multiple requests are sent using the same refresh token within a short amount of time, a race condition may prevent all requests from go…

Thanks,
Will
