Your flow credentials file is encrypted using a system-generated key.  
If the system-generated key is lost for any reason, your credentials  
file will not be recoverable, you will have to delete it and re-enter  
your credentials.  
You should set your own key using the 'credentialSecret' option in  
your settings file. Node-RED will then re-encrypt your credentials  
file using your chosen key the next time you deploy a change.

If you are using mosquitto v2.x you need to modify the conf file to allow external connections.

It's been covered quite a few times (search the forum)
