Hi,
It works for me with current QGIS master if I paste this exact url in URI with HTTP/HTTPS/FTP type : http://latuviitta.kapsi.fi/data/dem10m/dem10.tif Did you not add the /vsicurl in URI field ? Else it's indeed an issue with your proxy settings. Could you try somewhere there is no proxy, see if it works ? Kind regards, Julien > Hi, > > I have a DEM file http://latuviitta.kapsi.fi/data/dem10m/dem10.tif on my > server.
