XMLHttpRequest cannot load https://matrix.org/_matrix/client/r0/publicRooms?access_token=mUgvcafuUK. Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://riot.im' is therefore not allowed access. The response had HTTP status code 502.
