Katalon linux console mode works, but randomly throws error "org.openqa.selenium.WebDriverException: chrome not reachable"

My script works fine 50% of the time, but every now and then it fails with this error:

The root cause seems to be:
Root cause: org.openqa.selenium.WebDriverException: chrome not reachable

I have not been able to find any reason for this random failing. Any insights or direction towards a solution would be much appreciated.
