What are the reasons for returning this error -->could not authenticate you","code":32


For some users,While posting from my app,it is returning error code 32.what will be the reasons for this error message,this is only for few users who are using my app,is it related to only authentication issue or any other reasons?


It could be related to their user tokens being invalid, or their machine time not being sufficiently accurate (OAuth is time-sensitive), among other things.


Please Check this scenario – User did two posts on twitter from our app on same day,one got successfully posted other is failed with the error message could not authenticate you.After this again they did one more post then it is posted successfully.
If user token is invalid then both posts should have failed,Would you mind to share exact reason for this error message.So that we can handle this in better way.
As of now we are retrying the post if it fails for the first time if we got this error, But after retrying also we are unable to make the post.
