Instagram API ra-authentication issue


My app lets users connect with their instagram accounts and import media to post on my app. The authentication with Instagram works well and I’ve managed to post media from a connection made. However, after 1 hour the connection with Instagram needs to be re-established and when i try to let users do the authorization again I the authorization doesn’t go through.

Looking to see if there is anyone who has successfully gotten past this issue and know what I can do to solve this / point me in any direction to being understanding how to fix it?
