TtsSay only to base station

I am trying to get Rhasspy on a Pi4 with Docker as the base station running. As the only satellite right now I want to use this mobile app, but I can't get it running. I think I tried a lot of different configurations, but I still don't get a response back, it only goes to the base station.

I use an external mosquitto docker container on the same Pi4 as the base station. It is connected with ioBoker/Node-Red.

My Rhasspy config:

{
    "dialogue": {
        "satellite_site_ids": "rhasspy-mobile-chris",
        "system": "rhasspy"
    },
    "handle": {
        "remote": {
            "url": "http://EXT_IP_BASE:8081/intent"
        },
        "satellite_site_ids": "rhasspy-mobile-chris"
    },
    "intent": {
        "satellite_site_ids": "rhasspy-mobile-chris",
        "system": "fsticuffs"
    },
    "mqtt": {
        "enabled": true,
        "host": "EXT_IP_BASE",
        "password": "pass",
        "site_id": "rhasspy-mobile-chris",
        "username": "user"
    },
    "sounds": {
        "system": "hermes"
    },
    "speech_to_text": {
        "satellite_site_ids": "rhasspy-mobile-chris",
        "system": "hermes"
    },
    "text_to_speech": {
        "satellite_site_ids": "rhasspy-mobile-chris",
        "system": "nanotts"
    },
    "wake": {
        "porcupine": {
            "keyword_path": "jarvis_raspberry-pi.ppn",
            "udp_audio": "INT_IP_BASE_DOCKER_CONTAINER:20000"
        },
        "satellite_site_ids": "rhasspy-mobile-chris",
        "system": "porcupine"
    }
}

The Log if I send a text with the "GetTime" intent:

My mobile app configuration:

Rhasspy IP: EXT_IP_BASE:12101
Enable SSL: false
Enable MQTT: true
Host: EXT_IP_BASE
Port: 1883
user:  ...
pass: ...
Siteid: rhasspy-mobile-chris
Silent Detection: false
Enable SSL: false
Enable notification: false
Use external Dialogue Manager: false

Maybe it is just my mistake based on lack of experience, but I really tried lots of different connections. Maybe my understanding is wrong that MQTT sends the answer back to the source?
