I have been using the ISY994 for several years with lots of successful automation. In fact it is still working and I am able to connect using MobileLinc and see that my devices and programs are working as expected.
 
	However I am now unable to access the console to see and modify my programs. It simply never appears although before today it has always worked. I can start the dashboard from the ISY finder, but not the admin console. The JAVA starts to run and then just stops. No console is displayed.
 
	I have (after reading all I can find in the FAQs and documentation and this site):
 
	1. Rebooted the PC I am using
 
	2. Rebooted the ISY994 along with all of the routers and switches
 
	3. Updated JAVA
 
	4. Cleared the JAVA caches (trace and log files, cached applications and applets, installed applications and applets)
 
	5. Checked the JAVA security (high) and added https://isy.universal-devices.com to the exception site list
 
	6.Verified that no VPN is running
 
	I have enabled the JAVA console and run with level 5 logging:
