If you run a browser on the machine running node red and put that in as the url it should work. That is the same as http://localhost:1880. It is not telling you how to access it remotely, it is telling you the address the server is bound to.
127.0.0.1 is the local loopback address for every device, This address has been shown the same in every release as far back as I can remember. Just try it. In your browser (running on the same machine that Node-RED is running) enter http://127.0.0.1:1880 and see what happens.
Ok. Didn't know that. My device is remote, not accessed directly, only via IP, which makes that of no value for me. Pretty sure I used to see the proper Dashboard IP address (using the LAN IP) on start up, maybe never noticed that "local loopback" one.
$ node-red-start
Start Node-RED
Once Node-RED has started, point a browser at http://192.168.49.92:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot

Starting as a systemd service.

Ah, just noticed the extra line at the top. I thought you meant it changed the server line.
Ooops, sorry.
Maybe I can ask you an off topic Q here. I have 4 unassigned groups in Dashboard I cannot find to delete. They appear in all ui items (drop downs, as [unassigned] ) but not in the right hand sidebar so I can't manage them (out). Also, there is a little note under the Dashboard layout dialogue box suggesting I "click here" to get rid of unassigned groups but clicking it doesn't do anything.
