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).
The error message seems to indicate that your browser is not supporting WebGL.What browser and version are you on?It's also possible that for your particular browser, WebGL support is turned off. Is there a proxy inbetween ?
I've tried firefox 73.01 and chrome 80.0.3987.116. I've removed all plugins/addons to rule them out.
There is no proxy involved. If I disable security.csp.enable in the firefox console then the map displays along with a security warning .
After your comments I've also tried changing some of the webgl settings in firefox, but that doesn't seem to make any difference.
If it helps, I've cut the appropriate request out of a screenshot from the Firefox Dev Console. The first one shows the request failing when security.csp.enable is set to true. The request underneath that shows the request completing when security.csp.enable is set to false.
thanks for raising this issue. So both these errors so seem to refer to a generic CORS-loading issue.
That "unable to initialize map" is often related to WebGL, but given the error-message (can't load worker-script), we should be able to rule out it's a WebGL problem. Usually, the error message would say something more (e.g. "can't initialize WebGL-context" or something along those lines).
Could you try the following?
Go to https://maps.elastic.co. Does the page load succesfully? This is a previewer-website that loads the map with CORS in your browser, similar to how Kibana would do it with the default settings.
If that works in both your browsers (FF and chrome), it's probably related to the Kibana install/configuration.
