It is probably blocked because you are accessing the editor from an address that is not `localhost` and you are not using https.

You will need to configure your Node-RED to use https. See the `https` option in your settings file.

Edit your settings file and search for the the https setting entry. Read what it says to do.

The first screenshot shows it is trying to load:

- `/home/pi/.node-red/privatekey.pem`

The second screenshot shows the file is actually:

- `/home/pi/privatekey.pem`

You may have also tried installing other npm libraries from your home folder as your screenshot shows both a `package-lock.json` as well as a `node_modules` folder Might be worth checking those to see if you have to amend an install elsewhere.

Have you tried searching for that error yet? You generated a 1024 bits key, where openssl nowadays requires a minimum of 2048.
