Hi.

I have installed a NPM - node-red-contrib-sonoff-server.

After that it all crashed. When I start up it now just stops as listed below.

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.

This is an error that the node hasn't caught. It is trying to start on port 443 - this requires root access generally (any port below 1024 requires elevated rights). I don't know that node, I would guess that you've missed some prerequisite for its installation or configuration.

As @TotallyInformation says it is an error that the node hasn’t caught that the author need to fix. You can open an issue with the author by following the link to the idea github page from the nodes page on [flows.nodered.org](http://flows.nodered.org).

If you want to get Node-RED working againInwould suggest deleting the node with you can do using the npm delete command from the same directory you installed it from

Hi.  
Change Websocket port in node from 443 to 1443.  
[sonoff.config.json](https://github.com/mdopp/simple-sonoff-server/blob/master/sonoff.config.json)
