Attempt to register shows never completed and i see a javascript error I enter the pairing code and wait 20 seconds. The UI shows no indication of success or failure. but the chrome console shows the following:

bundle.js?master-81:28 POST 503 (Service Unavailable)
bundle.js?master-81:52 Mixed Content: The page at '' was loaded over HTTPS, but requested an insecure resource 'http://localhost:8888/'. This request has been blocked; the content must be served over HTTPS.
analytics.min.js:6 POST net::ERR_BLOCKED_BY_CLIENT
/#/device/add?_k=kcfqxc:1 Uncaught (in promise) TypeError: Failed to fetch

Is this problem still persisting? I think we had some issues with our backend over the weekend.

i think it was resolved. thank you!
