I have a viz with a tile map - the geopoint data in the docs is found and looks fine.
However, no map is displayed.
Opening the Chrome dev console, I see a GET to https://otile3-s.mqcdn.com/tiles/1.0.0/map/2/1/1.jpeg which fails.
Many other GETs to the same URL also fail.
Typing the URL into my browser gives;
This site can’t be reached
otile3-s.mqcdn.com’s server DNS address could not be found.
Any ideas ?
