When specifying the URL(s) in your Automate test scripts, you will need to enter the complete URL - the protocol and the FQDN (Full Qualified Domain Name). For e.g, instead of specifying google.com, you need to enter http://google.com or https://google.com. Without specifying the protocol (http://, https://, ftp://, etc), your Selenium tests will fail and you will receive a 404.
