Can't open java applet component when connecting to the application through Load balancer F5
Hi
We have one new building and the workstations are connected to our network. There is two systems that has java applet components that when clicked, it does not load the java applet. But when connecting to the application server node directly, these java applet components are opened. Al other buildings in other locations are working fine even through the current F5. Only this site has the issue !!! Our collegues checked for the workstation configurations and also bring one workstation to our IT department building and connected to same applications through the same F5, it Worked without any issues.
I have one system for Oracle applications 12.1 that I enabled the java debugging console. The output showed exception
network: Connecting http://hrms.domain.org:8080/ with proxy=DIRECT

We are using BIG-IP 11.0.0 Build 8037.0 Final
The issue only happen for that building, all other buildings connecting the same F5 are working fine without any issues.
When opening the page directly from the application server, like http://node1.domain.org:8080 , the java applet is downloadable and can be displayed.
Kindly advice
Thank you C.
