Fiware Orion MQTT notification not working (anymore)

Question

I don’t know where to look anymore, maybe someone has an idea what’s going wrong?

I created an MQTT subscription on my Orion Context Broker:

{
"description": "Subscription to notify of all WaterQualityObserved changes",
"subject": {
    "entities": [{
        "idPattern": ".*",
        "type": "WaterQualityObserved"
    }],
     "condition": {
            "attrs": []
        }
},
"notification": {
    "mqtt": {
        "url": "mqtt://127.0.0.1:1883",
        "topic": "water-quality-observed-changed"
    }
}

}

I have both my Orion Context Broker and Mosquitto MQTT broker running locally in Docker containers. I get this when listing the subscriptions in my Orion CB:

[
{
    "id": "633bf12fe929777b6a60242b",
    "description": "MQTT subscription to notify of all WaterQualityObserved changes",
    "status": "active",
    "subject": {
        "entities": [
            {
                "idPattern": ".*",
                "type": "WaterQualityObserved"
            }
        ],
        "condition": {
            "attrs": []
        }
    },
    "notification": {
        "timesSent": 3,
        "lastNotification": "2022-10-04T08:47:55.000Z",
        "attrs": [],
        "onlyChangedAttrs": false,
        "attrsFormat": "normalized",
        "mqtt": {
            "url": "mqtt://127.0.0.1:1883",
            "topic": "water-quality-observed-changed",
            "qos": 0
        },
        "lastFailure": "2022-10-04T08:47:55.000Z",
        "failsCounter": 3,
        "covered": false
    }
}

]

As you can see “timesSent” augments when I PATCH the entity.

The strange thing is it worked before!

Any idea what I’m doing wrong?

Thanks.

The "The strange thing is it worked before!" sentence make me think it has to do with connectivity between container. I'd suggest to review all the involved connectivity (Orion -> MQTT broker, MQTT broker -> your MQTT subscriber). If that doesn't help, a re-deploy of all the docker containers could help.
