Error when uploading test execution in Katalon Studio

I am facing this error in Jenkins console when executing my Katalon Studio Test Suite Collection from remote Jenkins.

System is unable to send report to Katalon Analytics. Reason: Connect to :0 [localhost/] failed: Connection refused (Connection refused)	at	at	at com.kms.katalon.execution.launcher.ReportableLauncher.uploadReportToIntegratingProduct(	at com.kms.katalon.execution.launcher.ReportableLauncher.preExecutionComplete(	at com.kms.katalon.execution.launcher.ProcessLauncher.onWatchdogComplete(	at com.kms.katalon.execution.launcher.LaunchWatchdog.notifyProcessTerminated(	at	at	[CIRCULAR Connect to :0 [localhost/] failed: Connection refused (Connection refused)]

Is there any update on this please ? With this quality of support we will not be continuing with Katalon Studio at an enterpersise level. There are lot of open source solutions available in which we can achieve all these basic connections etc easily.
