Hey I managed to overcome this step by adding inbound rule in windows defender firewall, for the remote port on remote server.
Here’s my ticket now I’m stuck cuz katalon is still taking an older Java version while running test cases.
Build info: version: ‘3.141.59’, revision: ‘e82be7d358’, time: ‘2018-11-14T08:25:53’
System info: host: ‘’, ip: ‘’, os.name: ‘Windows 10’, os.arch: ‘amd64’, os.version: ‘10.0’, java.version: ‘1.8.0_181’
Let me know if it works for you. happy to help.
