Preflight response is not successful

Attempted to launch the Chemicals-in-Cosmetics example and got the following error in the console: [Error] Fetch API cannot load http://portal.graphgist.org/graph_gists/chemicals-in-cosmetics/graph_guide due to access control checks.
Failed to load resource: Preflight response is not successful

I tried a couple of other ones as well with the same result.

Hello @wolfgang-ldc can you check again and send a screenshot if you still have issues?

Unfortunately it still gives the same problem, see screenshots. I deleted the initial database and recreated it, ok'd the port changes, and tried again to run :play, then same issue.

OK, I'm able to produce some errors using safari:

Remote guide error: TypeError: Cross-origin redirection to https://portal.graphgist.org/graph_gists/chemicals-in-cosmetics/graph_guide denied by Cross-Origin Resource Sharing policy: Origin null is not allowed by Access-Control-Allow-Origin.
