SOAP webservice limitation

Katalon only can execute SOAP webservice from url, if its only with " ?wsdl" format. But for our project we need to change the end point as “http://eappda1:8680/amptx-integration/ws/erpEquipment.wsdl

Manually I have hit the end point (http://eappda1:8680/amptx-integration/ws/erpEquipment.wsdl?WSDL)to browser with authentication, and its showing the WSDL content. but when I click “Test request and verify” from katalon its throwing error

Note:
Webmethod URL is working fine with katalon
http://sdc-esp2sgt01.ads.westernpower.com.au:4848/ws/wp.entity.equipment.v1.wsp:Equipment?wsdl


, but when I change it to Java endpoint , then its not working.
