Hey all,

I'm able to connect to my ui from localhost, but another computer on the same network as me cannot connect when using :1880/ui. I've tried every ip address from the host ipconfig /all and nothing seems to work.

Any help would be greatly appreciated, thanks!

Sounds like a firewall or something else at play. We'll need more info, for starters:

- How is node-red installed (direct on computer? via docker? as a HA plugin etc)

- What OS is Node-RED running on?

what does `ipconfig` reveal?

what was the URL you used on the lan computer? (you can obfuscate the IP but its not really necessary)

can you show us the output of node-red when it starts (the text from the console)?

I believe that, by default, Windows firewall will not allow inbound connections. You will need to add an exception to the Windows Firewall.
