<![CDATA[Sync issue, 404 on https://sync.opera.com/ui_backend/oauth2/login/]]>Hi, like many other users, I can't seem to make use of the sync feature.

The dev console show's gives the following errors:

Acess to XMLHttpRequest at 'https://sync.opera.com/ui_backend/proxy/auth/api/v1/me' from origin 'https://www.sync.opera.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

Failed to load resource: net::ERR_FAILED

Uncaught (in promise) Error: Network Error
    at e.exports (createError.js:16:15)
    at y.onerror (xhr.js:99:14)

Also https://sync.opera.com/ui_backend/oauth2/login/ gives a 404.

Hope that helps!
