Can labrepl run on 0.0.0.0 instead of localhost

[ghost]

Hello,

I try to do this course on nitrious.io.
They want that the server you made runs on 0.0.0.0 instead of localhost.

So I changed to this :

(defn -main [& args](run-jetty %28var application%29 {:host "0.0.0.0" :port 8080 :join? false})
(println "Welcome to the labrepl. Browse to http://localhost:8080 to get started!"))

but still the server is not be found.
