Hi, has anyone been successful at using the "node-red-contrib-azure-iot-device" node to connect to IoT Hub using CA certificates? I have been successful to connect when using SAS key. Every time I try using certificates I get the "Device Provisioning Failed" message. Can anyone help? Please let me know.
