Author Name: Simon Planzer (Simon Planzer)
Original Redmine Issue: 20808
Affected QGIS version: 2.18.21
Redmine category:web_services_clients/wfs

---

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')
1. 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

Please test with QGIS 3.4 - QGIS 2.18 reached it's end of life.
