Jorge,
Which error for which invocation of the WFS driver do you get ? Your
below tries are already low level attempts.
e.g the below invocation works for me without any error with GDAL master
(in "ghcr.io/osgeo/gdal:alpine-small-3.7.0" Docker image too)
ogr2ogr tmp.gpkg
"WFS:https://irig-madeira.pt/postgresql/drote/public/baram_2020/cgi-bin/qgis_mapserv.fcgi?service=WFS";
The WFS driver doesn't use /vsicurl/ but /vsicurl_streaming/ . The
former requires HTTP GET Range request support, while the later doesn't.
and when using "ogrinfo http://something";, you are *not* using /vsicurl
or /vsicurl_streaming. You are using the hidden HTTP driver that
downloads locally the file before passing it to a driver.
I don't believe there is an issue with QGIS Server. It probably streams
its output (didn't check though), so it cannot know in advance the
Content-Length. The headers of the HEAD requests aren't particularly
helpful too. Looking at the ones of the GET request, I see
"Transfer-Encoding: chunked" for QGIS server, which is in line with a
streamed output and OK

Hi,
I'm getting errors with WFS calls to QGIS Server using /vsicurl/.
Against Geoserver I didn't notice this issue.
I can work on a solution, if the problem is on the QGIS Server side. I
would love to have a second opinion on this.
What I have found:
1) The is no Content-Length: header in QGIS Server answer:
curl -L -I
"https://irig-madeira.pt/postgresql/drote/public/baram_2020/cgi-bin/qgis_mapserv.fcgi?service=WFS&version=2.0.0&request=GetFeature&typename=ponto_cotado&srsname=EPSG:5016";

2) The is a Content-Length: header in Geoserver answer:
curl -L -I

Example of testing calls:
This works (without vsicurl):
ogrinfo

For a Geoserver layer, vsicurl is working:
ogrinfo
"https://wssig3.azores.gov.pt/geoserver/ows?service=WFS&request=GetFeature&typename=ef:EnvironmentalMonitoringFacility&version=2.0.0&srsname=EPSG:5015";

using driver `GML' successful.
1: EnvironmentalMonitoringFacility
Can I assume that the problem is the missing Content-Length header in
QGIS Server WFS answer? Should I file a bug about this in QGIS?
Regards,
Jorge
