Earlier today I updated a Gateway just fine. But now when I try to update a Gateway I am getting a CORS error:
Failed to load resource: the server responded with a status of 504 ()
(index):1 XMLHttpRequest cannot load https://update.bluz.io/update. No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://console.bluz.io’ is therefore not allowed access. The response had HTTP status code 504.
