Node-Red MQTT with SSL/TLS can't connect to broker

[Armin@netPI]

Yes if you use the "hilschernetpi/netpi-nodered-fieldbus" image as it comes and you have no HAT on your Rpi it will indeed report this error.

You could start the container differently on your Rpi with different parameters in order not to start the default script file which is looking for netPI or HAT:

docker run -it -p 1880:1880 -p 9000:9000 --device=/dev/spidev0.0 -e "FIELD=pns"--restart=always --network=host --entrypoint=/bin/bash hilschernetpi/netpi-nodered-fieldbus

Use this command line above to jump into the container and suppress starting the default start script file. No error will arise then.

After the container is now started, then please enter the command node-red which starts now node-red manually. There will be some warnings that can be ignored, node-red will start anyway and also the MQTT node can be used.

By this procedure you can use the fieldbus container and test MQTT. Of course the fieldbus node cannot be used in this constellation but this is not matter of this topic. You just want to test MQTT connectivity, right?

Thanks
