The log is saying:

error: Unauthorized (401)

So my first guess is that maybe the issue is that the RTSP server is rejecting connection attempts from Kurento

This rtsp url can be played in vlc player, but you need to modify the configuration of vlc player.to set [ Live555 stream transport] to [ RTP over RTSP ( TCP )], if not modified vlc player will popup a window prompting that the rtsp url needs authentication
