When connecting with a browser (Firefox 45 ESR) to an URL like https://[rocket_chat_server]/[random_name] user get no error report and is not redirected anywhere. He is connected but have no clue what to do.
Same thing happen in the demo server (see gif attached) : go to https://demo.rocket.chat/nothingthere and see by yourself.
User should be redirected to an error page, and see his sidebar so he would be able to join another room.
