Hi **Shoaib**,
First question: Do your instance settings respect the requirements mentioned [here](https://gluu.org/docs/ce/3.1.2/installation-guide/#system-requirements)?
Can you provide the following log files:
1. /opt/gluu/jetty/oxauth/logs/oxauth.log
1. /opt/gluu/jetty/identity/logs/oxtrust.log
Thanks,
Gasmyr.
