we are trying to communicate to an azure iothub via amqp over websocket from a java docker container inside an azure kubernetes cluster. Sadly it seems, that the container cant establish a connection while locally or even on another virtual machine (where only docker is installed) the container run successfully.
The network policies rules should allow all necessary protocols and ports to communicate with eventhub endpoint of the iot hub.
Does anybody know which switch we have to pull to "allow" the container from the cluster the communication with the iothub?
The only logs we have are this:
