Hi,
Restarting EES 6.5 was caused by firewall rules. Interestingly, EES 6.4 worked well on that firewall rules. I have policy base mode, and unblock specific ports and hosts the rest is blocked. Communication with ERA server was unblock, also DNS, HTTP and HTTPS was unblocked for all hosts. What other ports are required for EES 6.5 to work properly? When I applied the ALL in ALL out policy, EES 6.5 started normally and worked fine.
