Da kommt aber "application token is invalid"
Versteh das gerade nicht
Edit
" To get started pushing notifications from your application, plugin, web service, server, or anything else, you'll first need to register it (a free process) to get an API token. When registering an app, you'll be able to set its name which will be used as a default title for messages, as well as upload an icon that will appear with each message on device clients. Each application from which you are pushing notifications with should be registered separately and each will get its own monthly quota.
Example Application API Token: KzGDORePK8gMaC0QOYAMyEEuzJnyUi "
Muss ich die DS irgendwie noch registrieren?
