Hi All
I have followed through the Tech Support article on configuring our Portal for ArcGIS 10.4 to work with survey123.com.
Unfortunately when i try to login using a configured url as suggested in the doc I get this error:
https://survey123.arcgis.com/?portalUrl=https://location.sa.gov.au/portal

When I check the appid and redirects in Portal it all seems as it should
{"appId":"survey123hub","redirectURIs":["\\http://survey123.arcgis.com\\","\\https://survey123.arcgis.com\\"]}
Not sure what else to check or do? Any thoughts will be greatly appreciated.
Cheers
