As of Jully 11th, Mapquest has discontinued access to their free maps. What is the fix for this? This seems like something that needs to be configured within Kibana and associate an API key.
We have a fix coming in a release that should be released soon in the 4.1.x and 4.5.x version. We're also looking at possibly backporting the fix into 4.x versions, but that's still being discussed.
Thanks for the reference. Glad y'all are already on it.
