I am trying to use the Experience Builder 1.6 to connect to ArcGIS Enterprise 10.7.1. This seems to hang after I specify the clientID and portal url. Looking at the urls generated in Developer Tools, I can see there is an extra dot following the web adaptor name. (see below)
Has anyone come across this? When I connect to AGOL, there is no issue.
Have you tried dropping the '.' from the URL? I've not come across this issue myself, but 10.7.1 is quite a ways behind the versions being used in AGOL / EB 1.6, and it would not surprise me if there were some unforeseen compatibility issues.
Yes if I remove the '.' in the url, I can get a json response.
From the documentation, EB supports ArcGIS Enterprise 10.6 and later
