You realise that the address is different when accessed from another device, yes?

Then that is your issue.

When you access from the _same_ device, you are probably using the URL `http://127.0.0.1:1880` or `http://localhost:1880`. That will not work from another device because those are the **local** addresses. From another device, you have to use the external IP address of the device.

You aren't listening I'm afraid.

To access from another device, you have to use the correct IP address.

The log tells you something like this:

```auto
[info] Server now running at https://127.0.0.1:1880/red/

```

That is the LOCAL address. Try this from the command line and you will find the correct address:

```auto
ip address

```

If you are using localhost or 127.0.0.1 then you are using the local address. Have you tried what Julian suggested to get your external IP address and use that?

You’ve hidden the address is every screenshot so we can’t say for sure what is suggested. One of my pis shows the local network address there rather than localhost, for example. So it’s not always localhost or 127.0.0.1. Does the address you see match what shows when you do `ifconfig -a`, for either `eth0` or `wlan0`? And have you confirmed that the other computer or device that you use is connected to the same local network?
