Issue running App Search

I can run App Search with success in port 80. However when configured another port in parameter "app_search.listen_port" I receive an connection error in browser.
It does not look as a "network/firewall" issue because App server console show "http get" message. Should the redirect URL to "/login" to produce the problem ?

From the logs it seems like it still runs on port 80, otherwise I would expect to see

Redirected to http://hostname:1234/login

Did you remember to restart the app server after you changed the config?
