As new to Red Node when finally got it all up and running and one tutorial  
I then added the dimmer switch node,  
now all's just blank with  
**127.0.0.1** refused to connect.  
Try:

- Checking the connection
- Checking the proxy and the firewall  
ERR\_CONNECTION\_REFUSED  
well i've done all that, surely it cant be a reinstall

What modules are your using, what is expected to be at 127.0.0.0.1? Are you using a ZigBee dongle to transmit between the node-red computer and the Ikea dimmer?

Your post lacks a lot of details. Which operating system is node red running on? Where are you seeing the **127.0.0.1 refused to connect** message that you are seeing?

I'm not using any modules at present,  
at this address 127.0.0.1, I expect node-red interface  
no i'm not using any Zigbee dongle, however i downloaded the node as a tutorial, since i have numerous dimmer functions required with a project.  
I am using Windows 10  
I am seeing the error message when type the address 127.0.0.1:880 into the browser.  
the browser is "Brave"

Because that is not the correct port: 1880

Free tip: use the node-red editor to install nodes instead, hamburger menu \> manage palette \> install tab, search the node, install. (installing globally is weird).

on commandline enter (if you are on a pi):

`node-red-restart`

Watch the output.

Another question: Are you trying to open the Node-RED editor in the browser (on port 1880) on the same machine as where it is running?

As you might already know, in networking, the address of 127.0.0.1 means "localhost", or the current machine. If for example, you were to run Node-RED on a raspberry pi as a lot of users on this forum do, but were to access it from your computer, 127.0.0.1 will point to the current machine, thus the computer, rather than the pi. In that case, you would need to access Node-RED in the browser with the ip address of the other machine. I'm adding this as it would explain the error you're seeing, as on your computer it might not have a process running on that exact port.

Yes I am at presently, or will be shortly running the Node-Red on the same machine that it is hosted to understand how all this goes together and works now in "Node-Red" day 2,

just now reinstalling Node-Red to alleviate the issue, and start again.

My strategy? was every tutorial add a node or two, as the nodes that I will require for this project are nowhere near the list I have compiled earlier. I have been informed that there is a better way of installing nodes,

But now however after 90 or so minutes uninstall failure, I am used to software working

Okay, instead of using 127.0.0.1, use the IP address of the machine that node-red is on. I think this may help.

it worked fine on 127.0.0.1:1880 yesterday until i downloaded a module between node red tutorials. now im on install 4 with differnt issues every time, The survey stated 26.7% of Windows 10 users,thats around 220 windows 10 users in the poll, however i'm of the opinion that its not for windows at all, what operating system do you run Node Red

Look it is a voluntary survey, there could be 1 million windows 10 users and we wouldnt know it if they did not participate in the survey.

I gave you a suggestion:

> `node-red-restart`  
> Watch the output.

Because you are on windows, you need to use `node-red` on the commandline instead and watch it.  
I am pretty sure you receive errors when node red is started.

Can I ask why you're running node-red from an elevated command prompt? The default starting directory for a regular prompt is the `C:\Users\...` folder iirc, but for elevated prompts it defaults to system32.

How did you install node-red ?  
and the question from @afelix was: why do you run node-red from an admin powershell ?
