I and my colleague experience problem with Avocent KVM console was not launch on Internet explorer 11. This problem arise after reinstalling all software on my laptop.
I am tried to remote access one of the server using Avocent KVM, however i got error message “your security settings have blocked an application signed with an expired or not-yet-valid…” and it stop run.
First i look into internet security option and change some setting on ActiveX controls and plug-ins but the problem still exist.
I found later that the setting must be change within Java control panel. I just need to add exception site list as below picture, i add 10.130.24.1
After that my Avocent remote access working fine.
By the way i am using java version 7 Update 67.
