Same as the above issue. Using Excel PowerQuery, API the following errors is happening using the instructions here: https://support.kobotoolbox.org/pulling_data_into_excelquery.html
Details: "Web.Contents failed to get contents from 'https://kc.humanitarianresponse.info/api/v1/data/647322?format=json' (404): Not Found"
These steps always worked for me before today. The issue seems to be only with Excel as it seems to work using PowerBI.
