Missing tiles in Watercolor

[djorke]

Some tiles are missing. For example here: http://maps.stamen.com/watercolor/#15/43.3944/21.8352

If you try to load a tile that doesn't load, for example: http://a.tile.stamen.com/watercolor/14/9183/5997.jpg
you get this message: Service Unavailable

A simmilar thing happens with Terrain layer, but not with Ink layer (you can see in attached screenshot)

Yep, I have the same problem. It starts on zoom level 15, everything above renders just fine. Once you zoom in to 15, tiles just won't load (in my case, this: http://maps.stamen.com/watercolor/#15/52.3329/10.8328)

I have the same issue with zoom level 18.
"map -> image" (m2i) also fails with levels > 16 and does not show tiles.

http://a.tile.stamen.com/watercolor/18/138297/84727.jpg -> OK
http://b.tile.stamen.com/watercolor/18/138298/84727.jpg -> service unavailable
http://d.tile.stamen.com/watercolor/18/138300/84727.jpg -> OK

Same goes for https://stamen-tiles-d.a.ssl.fastly.net/watercolor/18/138298/84727.jpg

What is required to provide debug info?

• https://wiki.openstreetmap.org/wiki/Maperitive

  • 2.4.3 only retrieves level 17 tiles

Huh, so it seems the watercolor renderer is proprietary and there is no way to look into it or render tiles myself.

BTW, this is a duplicate, there are many older reports regarding this issue.

The issues are known, map data / tiles are 5 years old, support has ceased, the renderer is closed-source.
