Issue when running katalon on microsoft azure pipeline (VSTS)


I am trying to run my tests using Microsoft azure pipeline tool (former vsts). On the remove server, I have Microsoft agent and Katalon studio installed. I went through this article ( and repeated all steps described there and could successfully run tests on azure pipeline.

However, when test execution was done I found that all test cases failed because of his issues:
Unable to open browser with url: and Caused by: org.openqa.selenium.WebDriverException: unknown error: unable to discover open pages. So seems like the browser wasn’t get open for some reason.

When I login to the server, open katalon and try to run the test suite manually, everything is working just fine.

Have anyone previously run into the same issue?

Any help is appreciated.

By the way, server’s operating system: Window’s server 2016.
