cannot access node red ui url from different device

[Avishek Guha]

Hi,

I have a raspberry pi running raspbian jessie with pixel. I use an ethernet cable to connect my Rpi to my laptop and ssh into it for all work. The Rpi and the laptop share the same wifi. I have used node red in this arrangement to deploy a simple ui using 'nodered dasboard'. When I open a browser on the laptop and got o "http://localhost.1880/ui/" I can see the ui perfectly fine. However, I cannot reach it using a different device (like a mobile phone or a different computer).

Any ideas what may be happening?

Thanks in advance.

"localhost" is a way of referring to the same computer as you are typing it. 

If you want to access the dashboard from a different computer you will need to replace that with the ip address of the RPi.

But it will depend on how your laptop is  sharing the network connection you may find that you can't access it.

The better way would to give the pi its own connection to your network, either by using use the internal wifi (if your Pi has it) or a wifi dongle or a wired network connection.

Then any device on the network would be able to access your dashboard at anytime.

What url are you using to access the ui remotely? You may think that
you did not need to tell us as the answer is obvious but one man's
obvious is another man's WTF.

Thanks a lot, Mark. Sorry, I did not use "localhost", in fact I was using ip-address of the RPI. But it was sharing the computer internet. Once I connected the Rpi to the internet separately, I can access the url.

Best,
Avi

Hi Colin, I am using http://[RPI-ipaddress]:1880/ui/#/0 

But Mark's solution worked. Thanks.
