some issue after using katalon studio

We have three environments(, and and all of them running under https with same war file, only testing environment’s certificate is self-signed. I ran a test case (Login) via katalon studio from my notebook against on my laptop. After I close the katalon studio, I can’t login successfully. And I checked the server log shows “Caused by: PKIX path building failed: unable to find valid certification path to requested target…”
I have no problem to login to and only failed on from my notebook. All my coworker can login the websites from their computer without any problems. The situation only happens on my notebook. The only different is katalon studio not installed on their notebook. Can someone help me to solve this issue? Thanks,
