Unable to connect to Selenium Grid running on AWS EC2

Tags: , , , ,



I have a Selenium Grid up and running on an AWS EC2 instance. I would like to connect to this from my local machine using Java to fire off my tests via a RemoteWebDriver, however, I’m unable to connect to the server be it through SSH or the Public IP.

For example I need to access the instance on port 4444 for a url of http://123.456.78.910:4444/wd/hub this would then need to establish a connection and receive my tests.

Whenever I try to use the Public IP I simply get a time-out.

Any help would be greatly appreciated.

Answer

You are getting a time out because your port 4444 is blocked in the EC2 security group. Check below you have add that rule to you EC2 security group. You can either add 0.0.0.0/0 but I will suggest just add your IP as you will be the only one to access that port from your local and for better security.
