Yes I am using the appid and appsecret. I'm using the constructor as in the example, with the addition of the access token expiry date:

CurrentClient = new DropboxClient(accessToken, refreshToken, expiryDate, appKey, appSecret, config);

 

The access token returned starts with sl. and is 139 bytes long. The refresh token starts with 1y_ and is 64 bytes long.

Fetching data from the api works up to the expiry date, which was set to 2020-12-09 17:37:48. After that fetching data takes a few minutes (!!) before throwing the exception.

I found 2 possible culprits:

- My code wasn't properly "asynced", which I know I have to avoid: eg: ListFolderAsync(xxx).result(). I recursively converted all methods to async (which was a long way up), and got rid of the .result calls. (I know these calls result in timeouts when exceptions occur inside)

- In the Dropbox App console for our app, under OAuth section: The "access token expiration" was still set to "no expiration", which I now set to "short lived".

 

With these 2 updates, it now seems to run (with original accesss token still from yesterday).
