When I tried this with eclipse/selenium java and Fiddler, its working perfectly.

Did you have any proxy setup?

As discussed with the admin, there is no need of a proxy set up to hit the url.


Hi Katalon Team,

Any suggestions on how to solve my issue?


Can you provide me Katalon Studio logs? It’s available in these places according to your OS system

Windows (\config\.metadata\.log)

MacOS (file:///Applications/

By the way, can I just see your request a little bit? You can censor any sensitive information in that request :slight_smile:
