Answer 1

I think the url http://accountapi.internal/CardInquiry belongs to some LAN & is publicly not available to use. So when ever you are calling this URL it's not getting any name server register for this address. so you are getting the message "Couldn't resolve host". Try putting IP Address i think it will work.
