Dropbox API uses standard http error codes, in your case, 401 usually means that user access token expired or revoked and it should recreated,

All you need to do is re-authenticate end user dropbox account by doing next steps in this order:

1. your application basic authentication:

     client = new DropNetClient(Settings.Default.DropboxApiKey, Settings.Default.DropboxApiSecret); client.GetToken(); 

2. Let user login Dropbox with their account and approve your Dropbox app:

     string url = Client.BuildAuthorizeUrl(); 

3. Retrieve and save authenticated user token:

     UserLogin accessToken = Client.GetAccessToken(); Account.Token = accessToken.Token; Account.Secret = accessToken.Secret; Account.Status = AccountStatus.Active; 

last - save account data in your app - Account.Save()
