I am having the same issue with: Failed to load resource: A server with the specified hostname could not be found. https://mw-ci1-mapkitjs.geo.apple.com/admin/source-maps/5.75.101/source-maps/libs/mapkit.core.f5d12d.js.map At first I thought it was a CSP header issue not white-listing that server because it was a different server name than the mapKit server. But that is not the problem. I get the same errors in Safari on macOS and iOS. But no in the Chrome browser on macOS.

I am getting the same error messages. I see them in macOS Safari and iOS Safari. I do NOT see them in Chrome on macOS which seems odd. Anybody find a way to resolve this issue?
