问题
I have a docusign-sandbox account. I am trying to integrate docusign with my application and am using JWT Grant for authentication in java. I got a sample code from https://github.com/docusign/eg-01-java-jwt and it works perfectly for an hour and then the API starts failing.
Any idea how I can tackle this issue?
I'm getting the below error
I already tried changing the Token expiry time from 1hr to other lesser values(5 min, 30 min). Even then the APIs start failing exactly after an hour.

Found a way around the problem.
The access token was being generated but for some reason it was not updating the token in the ApiClient Object and was using the old token only. So now I am just creating a new ApiClient Object every time the token expires instead of replacing the old token with the new one.

The jwt grant returns an access token that is only valid for 1 hour. After that, you need to generate a new token for another hour.
Call the example's checkToken method before each API call. It should create a new access token as needed.

You'll need to debug to see what's happening. Is the checkToken method obtaining a new access token after 50 minutes (it should be using a 10 minute buffer time). Is the new access token being used?
