DROPBOX API V2 CODE

I thought the DropboxClient would do 'it's thing' using the initial access and refresh tokens. It concerns an MVC webapp, and the dropboxclient is newly instantiated on every use. Using the it works for a while (a few hours after initial usser auth), but the next day it fails with ' : expired_access_token/'

The DropboxClient is instantiated with the Access_token and refresh token retrieved in the first part. dropbox-v2-api The API is generated programmatically, based on endpoints description JSON fetched from official docs. This endpoint includes an indicator - one of none, minor, major, or critical, as well as a human description of the blended component status. The tokens are persisted in the DB and to be used for longer periods (months) without the user needing to re-login Get the status rollup for the whole page.

The resulting POST http request gives me a code and DropboxOAuth2Helper.ProcessCodeFlowAsync provides me an access token and refresh token based on that code. I ask for user authentication (only once) using the DropboxOAuth2Helper.GetAuthorizeUri with OAuthResponseType.Code and TokenAccessType.Offline. Greg, I still can't get it to work for a duration longer than the access token's validity.
