My solution may be crude, but it works for me. Manually uninstall the geocoder and git clone it from here. Place the folder in the same path as map_widget.py. Then add the following function in the class OsmQuery(MultipleResultsQuery) in osm.py
def _build_headers(self, provider_key, **kwargs): """Will be overridden according to the targetted web service""" return {"User-Agent": 'My User Agent 1.0'}
This should be work.
