When I try to drag my map image onto my page, nothing happens. I get a CORS error in return. "Access to image at áddress' from origin '<a href="https://app.roll20.net" rel="nofollow">https://app.roll20.net</a>' has been blocked by CORS policy: The 'Access-Control-Allow-Origin' header contains multiple values '*, *', but only one is allowed.
