Shell Commands not working because sending to wrong IP address?

Hi,

for a while now, I tried to use shell commands without luck. Now I found this in the systemd log. Looks like the command is send to the wrong IP Address (192.168.2.2 is my synology)
Home Assistant runs on a raspberry pi 3 (192.168.2.25)

I fired the shell command with “Call Service” via HA UI.

Nov 25 03:12:23 raspberrypi hass[5236]: INFO:homeassistant.components.http:Serving /api/services/shell_command/restart_ha to 192.168.2.2 (auth: True)
Nov 25 03:12:23 raspberrypi hass[5236]: INFO:homeassistant.core:Bus:Handling <Event call_service[L]: service=restart_ha, service_call_id=1976470864-23, domain=shell_command, service_data=>
Nov 25 03:12:23 raspberrypi hass[5236]: INFO:homeassistant.core:Bus:Handling <Event service_executed[L]: service_call_id=1976470864-23>

This is my shell_commands.yaml

restart_ha: systemctl restart home-assistant.service

Whats going on?
