The response is a 404 error, indicating the file does not exist on the server. Could you confirm this for me?
The URL which you are using has missing ambari version hence it is an invalid URL. In your URL the ambari version is missing between the following strings in the URL updates/...../ambari.list
Please try the below URL:
