When remote users try to access the BNA web portal, they get a blank screen (with a P in the upper left corner). If I launch the web portal from the BNA host, I get the login screen. We have verified that port 443 is open. BNA appears to be responding, but the users get a blank screen rather than the login prompt. BNA 14.2.2 (IBM branded).
can you please post a screen-shot and exact error message and exact Release of used JAVA ?
you need Java x64
try with the Rel. 1.8.1 Build 13
