It looks like QGIS is attempting to download data in a bbox of mercator 
projected coordinates, while the overpass API is expecting WGS84 degrees.

This is surely a bug of the OSM plugin.

Maybe the plugin uses the project CRS as default for the bbox coordinates.

This might work:
- Create a polygon layer in WGS84 drawing a bbox polygon of the area of 
your interest with EPSG:3857 as project CRS and Openlayers background

- Delete the Openlayers background layer, change project CRS to 
EPSG:4326 and zoom to the extent of your polygon

- Download the OSM data

- Switch project CRS back to EPSG:3857, and load the Openlayers background.

HTH,
