In this case I think the problem is to do with the configuration of the WFS service, not with ArcGIS.
The Service URL is:
And the GetCapabilities request is like below:
or if you specify a version number like:
If you add the service URL to ArcCatalog, it will make a request like one of the GetCapabilities requests (above) and you will see the list of operations and available Features.
Take a look however at the response of these GetCapabilities requests, it tells us that to do a GetFeature (and other) request(s) we need to use a different URL
So now in ArcMap a request is made to the location referenced in the GetCapabilities response (this is the correct behaviour), but the
http://22.214.171.124:8080/geoserver/wfs URL does not appear to be publicly available, so no features are returned.
