I'm actually not a new user, have been using a ISY994 for about 8 years without problems. I always used IE to run the Java and I think my problem may be a missing or blocking PC config of some sort. I'm now trying to run the stand alone java.
Errors include:
telnet access works , but when I enable internet access I get "Could not configure the gateway."
ISY Finder finds my ISYs. I have one brand new that came with firmware 4.8.0 and my previous unit I upgraded to 5.3, both having the same problem.
ISY Dashboard gives errors "I/O Error: ProxyDevice" and "Socket Open Failed java.io.IOException: an Existing Connection was forcibly closed by the remote host"
ISY Admin Console fails immediately after authentication, flashing an error I can't catch.
What I've validated:
I'm running Java 8 update 271
I've shut down all virus software
I've reinstalled java repeatedly and cleared caches repeatedly
I upgraded the firmware of my old 994, did a factory reset, did a storage reformat, all seemed to have no impact.
The problem started on my 994 with 4.7.1. I upgraded to 5.3, same problem. I bought a new unit with 4.8. Same problem.
Other Considerations
The router is an Orbi, fairly new. I think I've used the 994 Admin console since that change, not 100% sure.
I've tested on a PC with Windows 10 and Windows 7, same results.
At this point I'm just trying to connect to the admin console. Both 994s are empty, no configuration restores.
Any ideas? I'm very used to all this stuff working without issues.
