Selenium Grid Error: Hub is Down or Not Responding on EC2 (AWS) Server

I'm trying to connect to an EC2 (Amazon Web Services) remote instance/server via Selenum Grid from my local machine. I have set

my local machine as a "hub" and can view the config on localhost (so I know it was set correctly).

However, when I try to set the remote server as a "grid" and connect to my local machine I am unable to do so succesfully. The

code I am using on the remote server is:

java -jar selenium-server-standalone-2.44.0.jar -role node  -hub http://REMOTEIP:4444/grid/register

The error I keep getting is: Unable to connect.. Hub is down or not responding..

I tried different variations like adding -hubHost and -host as parameter (as per the following threads on SO

Selenium Grid2 - Remote Node not connecting to HUB and

Setting up Selenium Grid) but whatever I do I keep getting the same error.

The other threads where all about connecting to a remote server that is not running on AWS platform. Perhaps there are certain

configurations needed for AWS? I have installed all appropiate jar files on the remote machine..

I have a dynamic IP but I don't think this is the problem because I have not changed my IP address (i.e, IP matches my current IP).

Thanks

you have to change the REMOTEIP with your adresse of the nodes. check when you configure the hub. with which adresse the nodes are registered. in my case: INFO - Nodes should register to http://xxx.xxx.xx:4444/grid/register/

So the code when you use the remote server should be: java -jar selenium-server-standalone-2.44.0.jar -role node -hub http://xxx.xxx.xx:4444/grid/register

java -jar selenium-server-standalone-2.44.0.jar -role node -hub http://REMOTEIP:4444/grid/register

The REMOTEIP(in your example) should be the IP of the hub, and not of the remote instance. Are you sure you have the correct IP set ?
