Is it possible to use NodeRED as functioning LAN https server?

Spoke too soon :frowning:
Everything worked without https when Scratch 3 running in browser on same machine as NodeRED but when trying to use across a LAN - it wanted webserver to be https again

So I edited my settings .js like this

...
// The `https` setting requires the `fs` module. Uncomment the following
// to make it available:
var fs = require("fs")
...
    https: {
        key: fs.readFileSync('ca.key'),
        cert: fs.readFileSync('ca.pem')
    },
...
    httpNodeCors: {
        origin: "*",
        methods: "GET,PUT,POST,DELETE"
    },
...

(my ssl certs are available here https://github.com/cymplecy/scratch_gpio/tree/v8 - stick them into /home/pi/.node-red)
