Error when tests start - can't open Browser

When I run my tests, the initial ‘Open Browser’ fails with the following:

Unable to open browser with url: ‘’

This was working a couple of weeks ago, but now I can’t run my tests.


More more info on this issue, I recently started running apache locally for my project and I get this Root Cause for the ‘Open Browser’ command failing:

(Root cause: org.openqa.selenium.WebDriverException: org.apache.http.conn.HttpHostConnectException: Connect to localhost:39019 [localhost/0:0:0:0:0:0:0:1] failed: Connection refused

Driver info: driver.version: CGeckoDriver)

I’m getting the same error since a few weeks:

2018-11-19 09:55:11 - [TEST_STEP][FAILED] - openBrowser: Unable to open browser with url: 'xxxxx'

I’m using Katalon remotly via command line. I don’t know if this is part of the problem
