Remote service layers not rendering

[timlinux]

Expected Behavior

I am trying to add a remote service layer from

http://data.fao.org/maps/wms

to a GeoNode 3.0 instance.

I tested with QGIS and the same service works nicely.

Actual Behavior

I used this layer for testing:

crs=EPSG:4326&dpiMode=7&format=image/png&layers=AQUAMAPS:cov03_42660&styles&url=http://data.fao.org/maps/wms

The same layer added in GeoNode shows a legend, but no map:

If I look in the layer view and use the network inspector I can see an error for the WMS call:

The url it is trying to access is:

http://data.fao.org/maps/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image%2Fpng&TRANSPARENT=true&LAYERS=geonode%3AAQUAMAPS%3Acov03_42660&STYLES=&SRS=EPSG%3A3857&CRS=EPSG%3A3857&TILED=true&ENV=&WIDTH=256&HEIGHT=256&BBOX=0%2C-20037508.342789244%2C20037508.342789244%2C0

Decoded:

http://data.fao.org/maps/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&FORMAT=image/png&TRANSPARENT=true&LAYERS=geonode:AQUAMAPS:cov03_42660&STYLES=&SRS=EPSG:3857&CRS=EPSG:3857&TILED=true&ENV=&WIDTH=256&HEIGHT=256&BBOX=0,-20037508.342789244,20037508.342789244,0

Opening that URL in my browser gives:

If I compare that with the WMS calls made in QGIS:

http://data.fao.org/maps/wms?SERVICE=WMS&VERSION=1.3.0&REQUEST=GetMap&BBOX=-180,-90,180,90&CRS=EPSG:4326&WIDTH=405&HEIGHT=807&LAYERS=AQUAMAPS:cov03_42660&STYLES=&FORMAT=image/png&DPI=72&MAP_RESOLUTION=72&FORMAT_OPTIONS=dpi:72&TRANSPARENT=TRUE

You can see the key difference is that the LAYERS list has prepended the word GeoNode:

Client	Layers
GeoNode Call	LAYERS=geonode:AQUAMAPS:cov03_42660
QGIS Call	LAYERS=AQUAMAPS:cov03_42660

If I take the URL generated by GeoNode and simply remove the geonode suffix in the layers list, the resulting URL correctly returns an image:

Steps to Reproduce the Problem

1. Add the WMS resource http://data.fao.org/maps/wms
2. Add the First AQUAMAPS layer that appears in the list
3. Open the layer view and the map is not shown
