Hi,  
this is my configuration:  
Rapberry 4 with rasbian 10  
Node red Version v1.2.7  
Node.js v12.20.1  
A very Simple flow nothing shows up on Debug Tab.

From the console of Chrome I find this websocket error:

What url are you using to access the editor?

The screenshot shows the editor is trying to use `ws://http//192......:1880/` as the url for its websocket connection back to the runtime. That is wrong - it shouldn't have that extra `http//` in it. But as the editor generates the `ws://` url from the url you are accessing the editor on, something odd is happening. Hence why I ask how you are accessing the editor.

Hi @knolleary  
I try to connect with ip “http:192.x.x.x :1880” and host name “[http://raspberrypi:1880/”](http://raspberrypi:1880/%E2%80%9D) with same result nothing to Show.  
I used more Browsers and conncect directly Pi4 to my laptop over ethernet.  
The only thing i did is edit ~/.node-red/settings.js for the credential secret.  
The error is my fault for debugging I lanched on the Chome console this script:

```auto
var webSocket = new WebSocket('ws://http://192.168.188.69:1880/');
webSocket.onmessage = function(data) { console.log(data); }

```

Thx

@zemmo a couple questions for you.

1. Did you install Node-RED using [the script in the documentation](https://nodered.org/docs/getting-started/raspberrypi)? If not, shutdown Node-RED and run it.
2. what device are you using to access NR? A Windows computer, Mac? A keyboard/monitir connected directly to the PI?
3. can you ping the Pi's IP address? Open a terminal window and type `ping 192.168.188.69 -c 3`
4. why are you usinig both the 'ws' and 'http in `var webSocket = new WebSocket('ws://http://192.168.188.69:1880/');`

Do not be offended, but I have to ask this as we do not know your experience level.  
The screenshot you posted shows the flow is not deployed, I have to ask whether you have Deployed it and then have clicked the button on the end of Inject node.

If you have then can you stop node red in a terminal and then start it again and copy/paste the startup log here please, including when you click the button on the inject node.

Have you ever had a working system?

Glad to be of help.

I recommend watching this playlist: [Node-RED Essentials](https://www.youtube.com/playlist?list=PLyNBB9VCLmo1hyO-4fIZ08gqFcXBkHy-6). The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
