Node red not loading
Hello. I was going to try to start learning how to use node red. When I click on the node red link in Webapps it just sits at "If your browser doesn't automatically go there within a few seconds, you may want to go to Node Red manually."
How might I go about finding what the problem is?

Can you try going to http://localhost:3000/plugins/signalk-node-red/redAdmin
I have been trying that and I get the same thing, just spinning loading.
I have been trying to go from my Win11 machine and to localhost on the Pi. The only thing I can see in journalctl is this: "TypeError: util.log is not a function" but I don't know if it is relevant or even how to log/debug it.
anything interesting in /var/log/messages?
On the Pi I think it is in journalctl but it is the same as when I run signalk-server from the command line (or similar, anyway.) there is some node rud stuff when I run it:
./signalk-server
The installed version of node (v23.6.0) is different than the recommended version (18 - 20). See https://github.com/SignalK/signalk-server/wiki/Installing-and-Updating-Node.js for more information how to upgrade.

node -v
v23.6.0
I think this is what got installed when I installed it through the plugin page in signalk
Or do I mean appstore?
has nothing to do with the appstore
"The installed version of node (v23.6.0) is different than the recommended version (18 - 20)"
So do I need to install a different version of nodejs? I don't remember doing anything unusual.
I am pretty sure that is the problem, but not 100% sure
I have not tested with v23
OK. Um.. I guess I can look that up, unless you happen to know how?
not off the top of my head
@Teppo Kurki have you seen this?
OK. So it was fairly straight forward by removing the newer version:
sudo apt remove nodejs
And then going through the setup instructions as linked from the signalk Pi setup page. Node red is loading now with v20.18.1. Thank you.
I remember seeing something way way earlier related to a fresh Node version and NR
