Hi I am using openfire 4.3.2 and I am enabling stream management while connecting to openfire using

xmppConnection.setUseStreamManagement(true)
xmppConnection.setUseStreamManagementResumption(true)

and here are my Servers Properties

here the issue if i suddenly got disconnected and at same time if some send me the message and i reconnect to ther server before the end of the session then i am not getting those messages any suggestion how can I solve this issue??

EDIT
I Found one thing If I didn’t close the app just close the network connection and after reconnecting to the internet all things work fine but if I closed the app message are not coming on time.
