Running F5 VPN or F5 EPI on the webtop page for the first time, Microsoft Internet Explorer v11 (IE11) spawns a pop-up window with text 'web page cannot be displayed' and does not close it automatically. The window must be closed manually.


Window does not close on its own, and must be closed manually. Might cause confusion.


The issue happens only when all of the following conditions are met: -- Microsoft Windows 7 operating system. -- IE11. -- F5 VPN/F5 EPI not installed. -- APM site is in trusted sites list.


None. However, if any of the conditions are not met, the window closes automatically.
