Errors in survey123.arcgis.com when using Portal 10.7.1

PeterKT

We have a newly established 10.7.1 portal - behind a firewall and I'm having trouble connecting it to survey123.arcgis.com

I've followed the instructions Use Survey123 with ArcGIS Enterprise—ArcGIS Survey123 | Documentation 

I've managed to publish a demo survey from Connect to the portal.  

I can login to the survey123.arcgis.com and I can see the survey on my Portal.

But as soon as I get into any of the tabs it just sits there and sometimes gives errors.  Tracking the traffic I'm getting a few requests failing. That when those requests are opened independently they work. 

We've added https://survey123.arcgis.com/ to the cross domain in the ArcGIS Server admin

Restrict cross-domain requests to ArcGIS Server—ArcGIS Server | Documentation for ArcGIS Enterprise 

We've added https://survey123.arcgis.com/ to the "Allow Origins" in Portal settings.

 

Anything I'm missing?

Hi GIS Unit PSBA‌,

It seems that when connecting to your 10.7.1 portal on the Survey123 website, the website can get information from your portal, e.g. the form item's details, but it cannot get information for the underlying feature service of the form item.

Can you please provide more information to help us investigate?

1. Just to confirm, the machine that the browser works on can access the behind ArcGIS Server, right? "That when those requests are opened independently they work. ", did you mean just double click the red request in the screenshot and open it in a new tab of the browser can return correct result?
2. Does the survey use a hosted feature service in the portal or a non-hosted feature service directly from the behind ArcGIS Server?
3. Does this issue occur just after 10/15 (we had the 3.11 release deployed on 10/15) and the workflow works as expected before 10/15 or you just set up the environment on 10/15 and we cannot know if it works with the previous 3.10 release?

Thanks,

Zhifang
