Had the same problem after starting.
Just start beef with the command (or just click on the icon) and let the console opened.

Then move to your browser and type in your local IP (not localhost) with the port "3000" and "/ui/panel" OR "/ui/authentication".


Give it a try, should work now ;)

i correct the bug just by restoring my old kali 3.14 its seem's that the probleme was in the new kali edition !

Maybe it is to late to answer to the original author but in case someone else needs it.

Try disabling the DNS extension. You can disable it in config.yaml by setting beef.extension.dns.enable: false (near the end of the file).

Answer found at the official GitHub BeEF page.
