Can not reach IP:1880 node red with my Raspberry PI4 eth0

General

Hello,
I have used not red on my Raspberry PI4 (192.168.1.161:1880) using wifi without any trouble. Now I want to put this Raspberry on my network via eth0 (ethernet cable). My router DHCP gave it an other IP (192.168.1.141). Putty and port 22 works perfectly on this IP but I can not reach 192.167.1.141:1880....!!! somebody knows why?

Thanks Collin,
I got this message when I type "node-red"
[warn] Projects disabled : editorTheme.projects.enabled=false

I fixe it with editorTheme/projects/enabled: false
changed it to I fixe it with editorTheme/projects/enabled: true

But it still does not work

now I have:[warn] No active project : using default flows file

ans I am stock!

Check the priority in /etc/dhcpcd.conf

Lowest metric has priority.

Do yourself a favour and either tell your router (if you haven't already) to give the Pi a fixed IP address or use a fixed IP address outside the DHCP numbers. That way it won't suddenly change one day.

For access, check that you are not blocking ports with a local firewall on the Pi (e.g. IPTABLES). Also check that you aren't using a proxy.

What is wrong with that? Are you trying to use the Projects feature in node-red?

That is because you have enabled the projects feature but have not defined one.

Back on the subject of the thread, how did you install node-red?

What does the command
ip a
show?

Can you show us the command window output that you get when you stop node red and start it again in a command window?
