[Fabric] failed to download settings Error Domain=FABNetworkError Code=-6 "(null)"

I create a blank project with cordova-plugin-firebase with same version “cordova-ios”: “6.2.0” and it’s work well but there is always this bug.
My question is: why my app does not open anymore with firebase and blank app works well?
