404 with wrap-proxy

Here is my handler. Got a 404 on /remote.
(-> #'routes
      (wrap-proxy "/remote" "http://www.lequipe.fr/")
      (wrap-session)}))

(defroutes routes
  (GET "/t" {c :context} (redirect (str c "/index.html")))
  (GET "/counter" [] counter)
  (GET "/sse" [] sse-countdown))

What could go wrong ?
