I had created dropbox API "sg wifi gateway" 2 month back. and used TI library to get the list of file from the Dropbox server using OtaClient_UpdateCheck function using the TI library to update the firmware remotely. but unable to get any update even the update is put in the apk folder. Since 2 months everything works well. but from last 4 days we are facing issues as we are unable to get the update from the dropbox server. If we create a new APK "adfgtre". everything works fine. But since the update is given to previous device is with othe API "sg wifi gateway, we wanted same API to work with the previous generated Token. Please, help us to fix this issue.

For instance, is the API indicating that your access token itself is invalid? By default, Dropbox API access tokens for your app(s) don't expire by themselves, but there a number of different ways that a Dropbox API access token can become invalid:
