Can you check if port 4040 is actually used? If it used the next available one would 4041. For example below Zeppelin uses it
*netstat -plten|grep 4040*tcp 0 0 :::4040 :::* LISTEN 1005 73372882 *10699*/java *ps aux|grep 10699* hduser 10699 0.1 3.8 3172308 952932 pts/3 SNl Jul30 5:57 /usr/java/latest/bin/java -cp /data6/hduser/zeppelin-0.6.0/ ...
