Can't open java applet component when connecting to the application through Load balancer F5

Hi CuteDBA, I agree with Kevin that something is probably different about the new building, most likely a firewall setting is blocking a tcp port that the applet needs to connect to the big-ip.

If you need assistance with capturing network traffic and decoding what is missing, you can certainly open a Support case with F5 Support. They are experts with helping capture traffic and decode what is going on ( or what's missing ). If all the other buildings are working fine, it is probably not an F5 issue, unless there are iRules or filters based on client IP addresses on the BIG-IP like Kevin suggested.

Thanx, Chris.
