In ArcMap 10.5 we included a WFS Service in a ArcMap project with the data interoperability tools. Recently we updated to version 10.8.1. Unfortunately the properties for the proxy server are missing now in the dialog for adding a WFS with the data interoperability tools. Does any one have a clue how I can insert a WFS in ArcMap 10.8.1 in accordance to our enterprise proxy server?
