I cannot get the OpenStreetMap -> download data... to actually download.
It acts like there is no problem, says the file is 0MB (it is actually 1KB) and it can be opened as a vector layer, however, the vector layer says there is no data.
I have ensured that it is in EPSG 3857 and the "on-the-fly CRS transformation" is enabled. The scale of the area is 1:500,000 as said by the QGIS website to test this.
The lecturer demonstrated it using 2.14.3 and the file he saved was about 17.5MB so around 17MB is the expected size for this.
