Errors accessing layers from endpoints in WFS

I have no problem accessing my servicepoints layers in WMS, either in QGIS (even without the specific SH plugin) or on OGC compatible webmap client (called MapStore), but it does not work well for me with WFS. Both clients access the two Sentiel2 sources, but loading them brings error messages. Eg for QGIS:

Layer S2.TILE : Download of features for layer S2.TILE failed or partially failed: Download of features failed: Error transferring[mytoken]?SERVICE=WFS&REQUEST=GetFeature&VERSION=2.0.0&TYPENAMES=S2.TILE&COUNT=100&SRSNAME=urn:ogc:def:crs:EPSG::4326&BBOX=7.6846740374496072,-5.12473906734211671,7.70836719414182348,-5.07859648921711671,urn:ogc:def:crs:EPSG::4326 - server replied: Bad Request. You may attempt reloading the layer with F5

The URL you have posted is not in line with our specifications, specifically the SRS name and geometry.
This works:,-5.12473906734211671,7.70836719414182348,-5.07859648921711671

That said, I would recommend you use Catalogue API as it is better and faster.
