I integrate my Katalon with external tools such as git via proxy.
a. I have setup the proxy settings to connect to internet via internet browser.
Result: able to connect to github repository

b. I have setup the proxy settings in Katalon via Window > Katalon > Git.
Result: able to connect to JIRA analytics but unable to Clone Project via the git integration icon.
I get the error below from the .log file:

java.io.IOException: Unable to tunnel through proxy. Proxy returns "HTTP/1.1 407 Proxy Authentication Required"
