Refresh Token expired

bszt123 Здравко is correct; this error is referring to the access token being expired, not the refresh token. When you get this 'expired_access_token' error, you should use the refresh token to get a new access token. If you're using a Dropbox SDK, the SDK will do this for you automatically, as long as you supplied the necessary credentials (e.g., app key, app secret (if not using PKCE), and refresh token).
