source connection to Eclipse Ditto

[gogardas]

Hi! I have created a DT example and I am receiving data in MQTT Explorer. But, I can't see data in Grafana OpenTwins (dynamic data). On website, there is a comment: "If the messages are being received, then the problem is in the source connection to Eclipse Ditto. Check the connection logs with http://:/api/2/connections/mosquitto-source-connection/logs. The Eclipse Ditto ip and port are obtained the same as mosquitto's, but since Ditto has more than one service, you have to query/expose the nginx one."

Here is the log I received:
{
"connectionId": "mosquitto-source-connection",
"connectionLogs": [],
"enabledSince": null,
"enabledUntil": null

Morover, when I put in python code the MQTT broker address, I am receiving the error (with broker = "localhost", the code runs without problem).

Hi, are you using minikube? When using minikube, you must use specific URL
Try using this https://ertis-research.github.io/opentwins/docs/installation/using-helm#configuration

Hi @sergioinf. Yes, I am using Minikube, and I'm using the proper URL and port number (obtained by minikube service --url). However, the dynamic data are not populated into the Grafana DT model (but I can see data in MQTT Explorer under the telemetry# topic.)
