Hi,
I can’t open Node Red UI or a blank page will be open when I try to open the web UI.
All the other addons works fine.
I have the latest HA Supervisor and Node red addon installed.
My Node Red config looks llike this.
Note: In order to use the http_node you will need to expose Node-RED using a network port in addition to ingress. The HTTP nodes will also be presented under /endpoint/ as shown in the UI. If using the node-red-dashboard module this will also be hosted under this path and will use any credentials set here.
Maybe try it without these first, and also check if it maybe an issue with ssl by setting ssl: false
Did you also try http_node & http_static blank?
Otherwise just deinstall and reinstall. I had that happen sometimes with other addons that suddenly work correctly after reinstallation.
Why’s the server running on port 46836? Shouldn’t it run on 1880?
If you go to the IP address with port 46836 can you get to the editor that way?
Update- After checking the release notes it appears the addon version of Node Red is supposed to run on port 46836 and then use ingress to access Home Assistant, so not sure what could be going wrong here. There was some posts about people having issues accessing the editor on the Node Red Add On thread starting here after that change was made -
No, this is not the first install of the Node Red addon.
I have been reinstall my host computer and restored a backup/snapshot where I hade Node Red installed.
Node Red have been working before.
I tried to uninstall and reinstall the Node Red addon. But no different.
I also tried different configuration of http_node & http_static. But no different.
@mwav3 that is strange?
I run my HA supervised on a computer with ip-address 10.0.1.3 and logg in to HA with 10.0.1.3:8123.
I can try http://127.0.0.1:46836.
But of course would I like to change to port 1880 and the ip-address
Have you tried another browser or computer? If the problem is still the same you could try a full remove and reinstall
Export all of your flows to a file. Then remove nodered. Then inside you config folder rename the nodered folder. This contains all the configuration information for node red and it persists over un installs
127.0.0.1 is the “loopback” address, and just points back to the machine you’re currently on. It might work if you were on the actual machine home assistant is installed on, but wouldn’t from a different one. With ingress, Node Red shold show up as an option on the side menu and you should be able to pull the editor up from anywhere you see your home assistant page
If you have 1880 listed in the addon configuration settings in the supervisor tab, it should put the editor on port 1880 as well. The log would still say 46836 but home assistant would put up the page on 1880 in the background. So if ip is 10.0.1.3 it should pull up the editor at 10.0.1.3:1880
That should all happen seamlessly to the user without them having to do anything else besides set the config properly in the addon settings on the supervisor tab. If something went wrong, best to follow the advice from mikefila above to export flows, rename folder, and reinstall.
If you can’t get access to the editor the flows are stored in a flows.json file and can be restored from there. That file is in the config/node-red directory.
What I would do first is uninstall the add-on. Then rename the old node red directory to something like node-redold. Reinstall the addon- at that point you should have a clean slate.
Then in the editor, go to import. You can use the file editor to navigate to node-redold and open the flows.json file. Copy the entire contents of the flows.json file and then paste it into the clipboard part of the import menu in your empty new node red instance.
You’ll probably have to reinstall any palettes and setup your credentials again for any flows.
I’m assuming based on your logs and issue there must have been some corruption in the old config, or it wasn’t compatible with your new install. Maybe you went from an rpi to another system with a different architecture and its creating a conflict. The more you try and copy over from the old config, the more likely you’ll carry the problem over. Hopefully importing the flows doesn’t just keep crashing the editor.
Okay @mwav3 I have tried to reinstall the NodeRed addon and renamed the NodeRed folder and reinstall the addon again.
But with the same result
Only a blank page when I try to open the NodeRed UI with a Bad Gateway error!
This is how my NodeRed logger looks like after the addon has been reinstalled.
