Hi all,
For the project I’m doing I’m using maps from Stamen. I noticed however that they, as used in Bokeh, do not work with a SSL configuration. Long story short, I changed the following lines in tile_providers.py
_SERVICE_URLS = dict(
CARTODBPOSITRON='https://tiles.basemaps.cartocdn.com/light_all/{z}/{x}/{y}.png',
CARTODBPOSITRON_RETINA='https://tiles.basemaps.cartocdn.com/light_all/{z}/{x}/{y}@2x.png',
STAMEN_TERRAIN='http://tile.stamen.com/terrain/{Z}/{X}/{Y}.png',
STAMEN_TERRAIN_RETINA='http://tile.stamen.com/terrain/{Z}/{X}/{Y}@2x.png',
STAMEN_TONER='http://tile.stamen.com/toner/{Z}/{X}/{Y}.png',
STAMEN_TONER_BACKGROUND='http://tile.stamen.com/toner-background/{Z}/{X}/{Y}.png',
STAMEN_TONER_LABELS='http://tile.stamen.com/toner-labels/{Z}/{X}/{Y}.png',
OSM='https://c.tile.openstreetmap.org/{Z}/{X}/{Y}.png',
WIKIMEDIA='https://maps.wikimedia.org/osm-intl/{Z}/{X}/{Y}@2x.png',
ESRI_IMAGERY='https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{Z}/{Y}/{X}.jpg'
)
to
_SERVICE_URLS = dict(

)
i.e., I changed http://tile.stamen.com to https://stamen-tiles.a.ssl.fastly.net. At least for my case (STAMEN_TERRAIN) it works. I got the new URLs from the Stamen website, maps.stamen.com
