Cloud Agent Error: Couldn't resolve host. Make sure the domain is publicly accessible or select a different agent.

@Shilpi Sinha The endpoint url we need to paste is in Current Value. I had also posted in first column instead of Current Value (Second column). Upon correcting this I was able to complete the step without any error. Hope this helps anyone encountering same error doing the challenge.
