App Never Loads When Using Kobiton

Hi, I’m trying to run a simple log in, log out test on an application. However, the app never seems to actually load. It runs for a really long time then eventually fails due to the following…

"Root cause: org.openqa.selenium.WebDriverException: Unable to parse remote response:

502 Bad Gateway"

I’ve tried using a different app and that one was able to load. Is there any particular way you’re supposed to setup an app for testing with Kobiton/Katalon? Thanks.
