Unable to listen on http://127.0.0.1.1880

I am running node red in window 10. Initially, I did setup node-red in the task scheduler on boot up event. I am facing difficulty to view node-red cmd to view my console.log. Therefore I delete task scheduler. But still unable to view console.log because of port in use. But I am able to run node-red in 10.0.0.1:1880

netstat -in
Check for the 1880 port.

Did you reboot after removing the task from task scheduler ?

in the title did you reall mean http://127.0.0.1.1880 or was that a typo and you meant http://127.0.0.1:1880?

4

yes, i did reboot

5

Its typo error. Actually its http://127.0.0.1:1880

Have you tried using a web browser and seeing what that page contains?

It’s an easy way of eliminating the possibility of node-red is still running on your machine

Hi, I did try on broswer with 10.0.0.1:1880 and 127.0.0.1:1880. Both shows Node-Red Flows. But cmd still persist with the same error after many attempts.

So node-red is already running, which is why you get the error

2 May 14:38:18 - [error] Unable to listen on http://127.0.0.1:1880/
2 May 14:38:18 - [error] Error: port in use

because you can't run two copies of Node-RED on the same port.

If you reboot the machine and this happens then it would appear the task scheduler (or something else you have configured such as pm2) is starting Node-RED.

Task Manager or RUN resmon.exe (https://en.wikipedia.org/wiki/Run_command). I did run resmon.exe to monitor Overview tab and Network tab.

In the Overview tab, I am to view node-red is running and able to see port 1880 is active in the Network tab.

I did end task and restart the pc then open cmd and run node-red. It's working.

Thank you to all. Do appreciate most for your support.
