listen EACCES error about wstunnel HOT 2 CLOSED

I found this is my environment issue due to on OpenShift.

I change the following line in wst_server.js

this.httpServer.listen(port, process.env.OPENSHIFT_nodejs_IP, function() {

However next error happen when I send tcp over tunnel (I am tunneling redis connection)

node wstt.js -s 8080 -t 127.3.61.129:13679

The root cause was that your TCP connection failed, and due to bug in the code, the error shown was "no method '_reject'".
