Katalon can't open Safari Browser on Mac


I installed Katalon Studio 8.5.3.alpha on my MacBook (Ventura 13.1) and want to execute tests with Safari.

I get the following error:

=============== ROOT CAUSE =====================

Caused by: org.openqa.selenium.WebDriverException: java.net.ConnectException: Failed to connect to localhost/0:0:0:0:0:0:0:1:29315

I already tried the steps described here: How do you enable/allow safari browser to run test

but it’s still not working.


It seems like Katalon cannot access to the link you have entered. Can you double check by calling that url in Chrome / Safari manually? As well, can you please try to run it in Incognito mode?


the problem was that I did not have administrator rights.Works fine now.
