How to enable or browse web service running on EC2 on local machine?

I have EC2 instance that has port forwarding enabled for EMR cluster. Ganglia monitoring service is already running on EMR. I am able to browse Ganglia from EC2 instance with following using "text browser" Lynx.

lynx http://localhost:5000/ganglia

However, I want to access this service from my local machine ( Mac Yosemite ). I did some research and found that I need X11 port forwarding. So now I also have X11 port forwarding enabled. 

echo $DISPLAY

gives me following on EC2 instance 

localhost:14.0

I am also able to run "xclock" and it launches clock on my local machine.

I tried to ssh into EC2 instance with this syntax .

 ssh -C -c blowfish -N -L:1050:myEc2Server:5000 myUser@myEc2Server

Then if I type http://127.0.0.1:1050/ganglia in google chrome I get message saying no data received.

Can anyone point out what is going wrong ? I tried verbose log from local machine to Ec2 instance and it has following message -

channel 2: open failed: connect failed: Connection refused

In short, I want to be able to see Ganglia from local machine. Any help is appreciated.

~Cheers

I tested an ssh command line from my own laptop (Mac Yosemite) and the following works

ssh -N -L:1050:localhost:5000 username@public-dns-of-ec2-instance

After this is connected, I verified using: http://localhost:1050/ganglia.

In your command line above, you may just need to replace myEc2Server with localhost or 127.0.0.1.
