@adrug16 @AjitPawar @DavidBroadhurst @YannickKonrad,
It looks like you are all new to the Atlassian developer community. Welcome!
I see that you seem to be facing the same problems with short refresh token expiration. While your subsequent request was relevant to the thread, we’re not getting new responses to your new issue. As such, I first recommend someone create a new post (in fact, I’m going to lock this one to avoid similar problems) with all the relevant details you can provide according to:
Even with that, OAuth problems are tricky because they involve secrets and often require Atlassians to go looking into specific logs to trace your requests for problems. As such, I would advise following up with our developer support where you can (and should) share your client ID & secret, along with any other details about the requests that would help us debug.
