Survey123 Website Does Not Display Data from Portal

[BrysonKoziell]

Running 10.5.1 Portal and trying to connect to Survey123 Website.  I can see statistics on my surveys, I can download the data from my surveys, but I cannot see the data on the Data tab or use the report writer. 

Error Message:

Failed to load https:/XXX.com/portal/sharing/generateToken?request=getToken&serverUrl=https%3A%2F%2Fcomet.pennichuc...: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://survey123.arcgis.com' is therefore not allowed access. The response had HTTP status code 401.

Hi Bryson,

It's a little hard to see with the way the URL auto-shortening has altered the URLs, but the 'Access-Control-Origin' indicates that your portal is not setup properly for cross-domain access, which is needed in the case of Survey123's website to connect to portal.  https://enable-cors.org  provides information on what is required, why, and how to implement.

I'm also using Portal for ArcGIS 10.5.1 with Survey123, version 3.0 and getting a similar issue.  My survey publishes OK, and I'm able to view it in my Survey123 app, but the CORS error occurs when I attempt to run the survey in a browser, whether that be IE, Firefox or Chrome: the same error occurs.  I've tried adding the following to my Default web site on the Portal server.  I've also tried adding them to the web adaptor only:

<add name="Access-Control-Allow-Origin" value="*" />
      <add name="Access-Control-Allow-Headers" value="Content-Type" />
      <add name="Access-Control-Allow-Methods" value="GET, POST, PUT, DELETE, OPTIONS" />

This makes no difference and same error occurs.  Here's the error message in my browser's console:

SEC7120 Origin https://survey123.arcgis.com not found in Access-Control-Allow-Origin header.

I've even tried this:

<add name="Access-Control-Allow-Origin" value=https://survey123.arcgis.com />

I've also tried with just Access-Control-Allow-Origin, without the Access-Control-Allow-Headers or Access-Control-Allow-Methods, but it made no difference.
