I continued testing and I verified that the SRS is set correctly (by doing getfeature without bbox and only maxfeatures=10 in the call). I also verified I am getting the correct data by this.
No change with the max-features in the map-file. In the xml file it seems to be needed.

Hello Lars, maxfeatures was my first guess... have you also turned ist it off (no maxfeatures)?Jörg Am 27.05.21 um 08:51 schrieb Lars Fricke:Dear All, as this list is a source of much deeper insight than I have into Mapserver, I would like to ask about a very strange issue I am facing. I am calling on a public WFS server I can query "by hand" fast and successfully every single time. Now I defined a Mapserver layer (see below) as an OGR layer in my WFS map-file and it does - on the same call - return data. But not reliably, more at random. I played with the connection-timeout and the maxfeatures and it seemed to have some influence but again, not reliably.
