Thanks @Vinh for the reply. I tried setting the value as you have advised.
Even I am getting the connection refused error. When I verified the log after setting the user preferences. Katalon is running the code with the proxyInformation which we set in the katalon studio preference - katalon - Proxy. is it overriding the proxy information I have provided using RunConfiguration?
Please find the log
