I am having difficulties upgrading my node-red installation. The following command (and others) all return a 503 Error when run:  
Running Node-RED install for user pi at /home/pi on raspbian  
bash \<(curl -sL [https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered](https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)) --node18  
with this result:  
This can take 20-30 minutes on the slower Pi versions - please wait.

With the same error? That suggests there is a problem with the pi apt repository. Show us what the command  
`sudo apt update`  
gives.

Can you open that in a browser? It is ok for me at the moment, so there is not a problem with the server.  
Can you ping the server?  
`ping deb.nodesource.com`

Edit: Obviously you can ping it, otherwise you would not get the 503 error.

Are they on the same local network?

Are you on a company network? If so then I suspect it is something on the network.

You have something very odd going on, as that is a different ip.

What about `dig deb.nodesource.com`

I agree it quite odd....  
I rebooted both router and Pi4. here's the output from dig on the pi4:

Yes, that is the problem. You have something very wrong with your DNS.  
What is in /etc/dhcpcd.conf? Watch the spelling, it is not dhcpd.conf or anything else similar.

I had set a static IP for this host in the past using /etc/dhcpd.conf. I eliminated these few lines from the file to allow the router to set the IP. After rebooting both the router and Pi 4 host. I checked the IP; it has changed to a new LAN IP, like you'd expect. Internet connectivity seems fine. However I still get the wrong IP when trying to connect to [deb.nodesource.com](http://deb.nodesource.com):

So I don't think it's a DNS error?

Pihole is disabled on my Pi4.  
the wget commnd you show here resolves to the correct IP address for [deb.nodesource.com](http://deb.nodesource.com), but my system does not. Note the output form my wget resolves to a different IP; hence the 503 error:  
wget -v [https://deb.nodesource.com/node\_18.x/dists/nodistro/InRelease](https://deb.nodesource.com/node_18.x/dists/nodistro/InRelease)

I haven't yet figured out why this happens.

Yes, I see that the DNS server reported by your dig command is 208.67.222.222 while nslookup uses localhost.

Does it make a difference if you specify DNS servers in your router - 1.1.1.1 or 8.8.8.8?
