Unable to execute desktop Web tests remotely on sauce labs

I am trying to execute a small test on chrome web browser on sauce labs, i have gone ahead followed the guide Settings>>remoteweb

Katalon version :- 5.2

Url used in remote web server :
tried below as well
**Remote web server type :
**properties set in the table:
**platform - Windows 8
version - 63.0
browserName - chrome

When i kick of the script run>> remote , i get the below error

org.openqa.selenium.WebDriverException: org.apache.http.conn.HttpHostConnectException
Connection timed out

The same script works well with local chrome browser on katalon

Is there any documentation available to connect katalon to work with desktop browsers ? or am i missing some step or parameter

I did search for the same issue on the forums could not find anything ,please point me to the solution if it already exists

Thanks in advance for ur response
