Description
Issue originally summarized against my own product as below (Apologies, the example requires an API for data.linz.govt.nz):
*QGIS 2.18.17
*
uri = 'https://data.linz.govt.nz/services;key=<API_KEY>/wfs?SERVICE=wfs&VERSION=2.0.0&REQUEST=GetFeature&TYPENAME=data.linz.govt.nz:layer-50221' layer=QgsVectorLayer(uri, 'test', 'WFS') layer.isValid() True
*QGIS 2.18.26
*
uri = 'https://data.linz.govt.nz/services;key=<API_KEY>/wfs?SERVICE=wfs&VERSION=2.0.0&REQUEST=GetFeature&TYPENAME=data.linz.govt.nz:layer-50221' layer=QgsVectorLayer(uri, 'test', 'WFS') # QGIS HANGS AND NEVER RECOVERS!!!
I do note a WFS2 source code change (https://github.com/qgis/QGIS/compare/final-2_18_20..final-2_18_21#diff-7f83d21b1d3b1afc39d33a7c9560cb59R439) between 2.18.20 an 2.18.21 monitoruf WFS2 responses. Perhaps related???
Anyone info you require please ask

- Note I have edited this to include a temporary API key (in above wfs url) for this service to support debugging
