Error during integration with analytics

Hi, I’m trying to integrate KS with katalon test ops, bu t when I try to connect I got an error message,
might it be provoked due to the fact that I’m a private network?
Is so, what should I do to prevent this error form happening again?
Thanks in advanced!

logs_error1
