Server on Linux, client on Windows does NOT work

[limenleap]

On the Linux server (64bit Ubuntu) I started it like this:
./mr2 server -p xyzabc -l :9999

(on the ufw firewall at Linux and even at the Amazon Networking permissions, I opened both ports: 9999 and 8980 )

I started a small localhost webserver at 127.0.0.1:8980

Then I started this on Windows
mr2 client -s 65.1.164.105:9999 -p xyzabc --serverPort 8980 -c 127.0.0.1:8980
But when I browsed to
http://65.1.164.105:8980

It does NOT connect

What may I be doing wrong? Thanks!

Additional info:
When I do ctrl-c on the Linux server command, I get this message after it quits: " use of closed network connection" Is that a clue?

I stopped the localhost server and thought of serving out a folder as a website. So I gave this command

mr2 client -s 65.1.164.105:9999 -p xyzabc --serverPort 8980 --clientDirectory C:\data\limenleap --clientPort 8980

But even that did NOT work. What should I do next?
