Pushover send no message

hello

i ve a problem with pushover, this action will not send any message.

in my pushover.cfg i added my key

defaultToken=here my Api Tokn Key from pushover.net (Application Screen)

# You need to provide a Pushover User Key to send to devices. If not here, than during
# the action call itself.
defaultUser= here my User Key from pushover.net (Homescreen)

# Name of the sending application (optional). Defaults to 'openHAB'.
defaultTitle=openHAB

if i use a rule like this

rule "Kasse Alarm"
	when
		Time cron "0/15 * * * * ?"
	then
	if (Bewegung_Kasse.state == 1)
		{
		sendBroadcastNotification ("Kassenzugriff")
		pushover("Kassenzugriff")
		Bewegung_Kasse.sendCommand(0)
		}
end

only sendBroadcastNotification works.

EDIT

Works now. Problem was the Android App
