I'm using the elastic supplied dockerised version of Kibana, version 7.5.2 which is working fine for general elastic management. I'm having issues with the Map functions.
When I try and use/create a map I get a blank map.
In Chrome I get the below error
Unable to initialize map
Failed to construct 'Worker': Access to the script at 'blob:https://mydomain/72f464b4-b547-4266-9957-09f76a82cefb' is denied by the document's Content Security Policy.
In Firefox I get a blank page with the warning triangle showing road_map cannot be retrieved "Network error when attempting to fetch resource". The dev console Network tab shows the GET to https://catalogue.maps.elastic.co/v7.2/ is not completing with CSP under "transferred".
Both the kibana container (via curl) and my web browser can access the catalogue.maps.elastic.co url. I've had a colleague try the website from a different machine and they get the same behaviour.
Is there anything I need to do to get the maps to show. I'm not a web developer by trade so I don't know if this is something i've missed in setup or an issue with the kibana docker image as supplied (or something else entirely).
