Hey Daniel,
I couldn’t replicate the issue on my site so we can’t consider this as a bug unless we receive several more reports. This is currently only a local issue or only on your end so you must use the working setup.
Technically, the error that comes out is 403 and that is related to the server. There might be some server configuration that is causing the issue. Try contacting your web host to check the server error logs and fix issues according to the error messages.
Thanks.
