Feature service error.

Hi,

We have recently upgraded our Geocortex to version 4.1.1 and we seem to be having issues adding Feature Layers from ArcGIS Feature Services.

The feature service that I have been attempting to use has been successfully used in the past version of Geocortex 3.15, however after the Geocortex upgrade we are getting this error message when we attempt to add it to the map:

/customer/servlet/servlet.FileDownload?file=00P6000000elti5EAA

Just curious to know whether this is a known bug or there is a new configuration in 4.1.1 that we have missed.

Thanks.
