Description

When a browser window is open and the NiFi UI is loaded, and then the server is stopped, the UI displays a page explaining that the connection is not available.

This UI page captures keyboard commands, so when the server is restarted, pressing Ctrl/Cmd + R does not execute the browser's refresh function. Rather, the refresh menu or toolbar item must be invoked using the mouse.
