I have upgraded my jaspersoft server from 6.2.1 to 7.1.3. My jaspersoft installation setup is on a clustered environment. It has 4 jasper servers. All the individual nodes are working fine in the serverand i am able to run report. However after upgrade i am able to login using the superuser credentials in the load balancer URL but the jasper server login page is not showing any details. I have attached the screenshot.
