MQTT plugin to The Things Network doesn't catch any data

I tried to setup a second MQTT connection from the MQTT plugin to The Things Network (TTN). The first connection is to a local 1.3.4 version Mosquitto implementation.

The connection is established but my device isn't receiving any data at all:

14:32:48info [pimatic-mqtt]: Successfully connected to MQTT Broker TTN
14:32:43info [pimatic-mqtt]: Reconnecting to MQTT Broker TTN
14:32:38info [pimatic-mqtt]: MQTT Broker TTN is offline
14:31:07info [pimatic-mqtt]: Successfully connected to MQTT Broker default

Using device:

{
      "attributes": [
        {
          "name": "GPS data",
          "topic": "+/devices/+/up/gps_1",
          "type": "string",
          "messageMap": {}
        }
      ],
      "xAttributeOptions": [],
      "id": "car-tracker-eugene",
      "name": "Car tracker Eugene",
      "class": "MqttSensor"
      "brokerId": "TTN"
    }

Also tried:

topic": "hello_world_test_eug/devices/ttndeviceeug/up/gps_1"

No data at all. The local broker still produces data for other devices.

While

mosquitto_sub -h eu.thethings.network -t 'hello_world_test_eug/devices/ttndeviceeug/up/gps_1' -u 'xxxxxx' -P 'ttn-account-v2.xxxxxx' -v

produces:

hello_world_test_eug/devices/ttndeviceeug/up/gps_1 {"altitude":72.8,"latitude":50.9471,"longitude":5.7778}

I also upgrades Mosquitto to 1.5.0 version and created a MQTT bridge to TTN, so al the traffic comes to the local broker.

Changes the device to the local broker:

    {
      "attributes": [
        {
          "name": "GPS data",
          "topic": "+/devices/+/up/gps_1",
          "type": "string",
          "messageMap": {}
        }
      ],
      "xAttributeOptions": [],
      "id": "car-tracker-eugene",
      "name": "Car tracker Eugene",
      "class": "MqttSensor",
    }

But also no data.

While:

mosquitto_sub -h 127.0.0.1 -t 'hello_world_test_eug/devices/ttndeviceeug/up/gps_1'-v

produces:

hello_world_test_eug/devices/ttndeviceeug/up/gps_1 {"altitude":72,"latitude":50.9471,"longitude":5.7778}

Who can help me out to debug/solve this issue?
