I've seen that my cloudboost app is constantly doing this call:
https://realtime.cloudboost.io/socket.io/?EIO=3&transport=polling&t=1455824292764-0
And this error is returned:
[Error] Failed to load resource: A server with the specified hostname could not be found. (socket.io, line 0)
How can I disable realtime?
You can disable realtime when you init your CloudApp.
CB.CloudApp.init('https://api.cloudboost.io', 'Your AppID', 'YourAppKey',{disableRealtime : true});
