Node-red will be used to pilot a LoRa gateway  
[warn] encrypted credentials not found  
[error] unable to listen on [http://127.0.0.1:1880/](http://127.0.0.1:1880/)  
[error] error: port in use

The restart flows =\> successfully restarted flow but no result in the debug messages + no result in IP:1880/ui ☹  
I've deleted « .node-red » repertory and restarted node-red, but it was the same with the new one.  
I've writen a credentialsecret in .node-red/settings.js =\> it was the same warn  
I've given to credentialsecret the value false =\> the warn was about the "Using unencrypted credentials"  
Then I would like to erase everything and start from scratch.  
How should I do?

This indicates a conflict, possibly a second instance of Node-RED already running

1. What computer is this?
2. What operating system does it run?
3. How did you originally install Node-red?
4. On what computer and with what browser are you trying to access Node-red?
5. What (local) IP address does the Node-red machine have? There is no harm in telling us this since it should only be accessible from within your home network.

You can safely ignore this warning

:1880/ui is the URL for node-red-dashboard. If you have not yet successfully run Node-red then you don't have the dashboard installed. (And anyway as a new user you should aim for the replacement dashboard @flowfuse/node-red-dashboard not the old one.)

To check whether node-red is already running, you could try to access it in a browser.

Or if you have access to it, locally or remotely, and running under linux; open a cmd session and type ps aux to view all running processes

It was that : a second instance of NR.
