Hi, It is also interesting that when I run the query again using WFS version 1.0 and network logging all four requests succeed but the layer is still invalid.
The getFeature returns a single feature with the following geometry: <gml:Polygon srsName="http://www.opengis.net/gml/srs/epsg.xml#27700"; srsDimension="2"> <gml:exterior> <gml:LinearRing> <gml:posList>389814.604 97465.168 389823.18 97454.59 389858.98 97463.67 389855.18 97472.01 389849.77 97481.28 389845.792 97486.125 389814.604 97465.168</gml:posList> </gml:LinearRing> </gml:exterior> </gml:Polygon> Does that give any clues? I'll head off and check it in my 3.16 version now.

However I don't really understand because requesting the data in the GeoServer layer preview works fine so I assume QGIS is asking something the layer preview does not?

I don not know exactly) has s NetworkLogger/Debugger. If you hit the F12 button, you will see all WFS-requests that QGIS is firing to the server. You can 'replay' these in a browser, and see if it returns valid GML (as in: save it to disk and then try to open it as vector data). Normally QGIS starts with a GetCapabilities request, then a DescribeLayer and then a GetFeature. You need that last one. In the Network Debugging window you can also see if the server maybe returns an error code (as: not 200). Does the Geoserver-layer preview work? As in can you see the layers there? Normally WFS/WMS from Geoserver play pretty well together with QGIS. Is there something special to the data? (curves, nonvalid geometries, ???)
