Hi em, could you follow up with this issue next week. Thanks em

wrongly configured Proxy ?

The proxy is set up and the other APIs are running successfully but this API always get 503.

I understand that your Proxy server is running OK. Fine.

Then, the configuration in your Katalon Studio for your test cases to be connected to the Proxy server might have something wrong.

Hi @jefribarutu03 ,

Have you had the workaround with this issue?
