I have a 7200 running 4.53c
I can't connect via browser because its giving me a java plugin error. I added the IP addr to the IE trusted sites but it still fails.
I was running Java 8 but uninstalled it to reinstall a version of 6. It still isn't letting me in. Keeps displaying java web start plugin.
Is it a java version issue?

Not a java issue

You'll need to add the ip address of the system to the compatibility list.
