Stamen Maps has Moved

[nateybear]

As of October 31, 2023, Stamen Maps are no longer available at the Fastly URL that they currently point to. The tile server is now hosted by Stadia Maps:

https://tiles.stadiamaps.com/tiles/{variant}/{z}/{x}/{y}{r}.{ext}

Where variant is now stamen_toner, stamen_toner_background, etc.

Since there is already a Stadia TileProvider, I imagine the path forward will be removing Stamen as a tile provider and adding the stamen variants to TileProviders.Stadia.
