External node red UI inside HA

Configuration
1

I moved my NodeRed from the nodered addinto a separate instance. Is it possible to still access the separate node red UI from within HA?

Will that work if the destination is only accessible on the internal network and I want to be able to access it externally through HA?

Depends on your setup. If node red is available through https and Home Assistant as well, then yes, otherwise no.

If you want external acces but keep it http, I suggest using a reverse proxy and link a subdonain to nodered.

Both are configured for HTTPS, I’m just not allowing node red through the firewall. Works fine on internal network but outside it doesn’t.

Should work, why don’t you just try it? :smiley:

7

I did, that’s why I’m here hah. When trying to access externally it puts up a “grey” screen in chrome saying 192.168.x.x took too long to respond (internal IP of modeled)

Can you show the config of the iframe panel?
