clod9 on EC2, accessin problems

js community,

I manage to install cloud9 on my amazon EC2 Linux distribution, but Im getting a hard time trying to access it.

I start cloud9 like this bin/cloud9.sh -l 0.0.0.0 -p 3131 And it starts

Then I access the cloud 9 with the following url http://ec2-XX-XXX-XX-XXX.eu-west-1.compute.amazonaws.com:3131/

And it gives me the following error

IDE server initialized. Listening on 0.0.0.0:3131
path.exists is now called `fs.exists`.

node.js:0
// Copyright Joyent, Inc. and other Node contributors.
^
RangeError: Maximum call stack size exceeded

I also, open the ports with custom tcp for the port 3131, in the security groups.

Am I, missing some configuration file or anything??
