There is quite a few nodes that need updates. Try to see if it starts in safe mode. Add --safe to the init commands on the addon configuration page.
If it does, start page by page, double click on a page tab, the bottom left of the dialog box will have a disable button.
I just restarted my instance of nodered and I also have
20 vulnerabilities (10 moderate, 7 high, 3 critical)
To address issues that do not require attention, run:
npm audit fix
To address all issues (including breaking changes), run:
npm audit fix --force
It’s been a while since I looked at my logs and assumed that was from additional nodes, it seems it’s “normal”.
Is this your first install or has it run before?
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.
@Mikefila
How do I export flows to file if I don’t have access to the NodeRed UI?
Remove NodeRed do you mean uninstall the addon ?
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.

Try disabling ssl in your config, see this post
Also try clearing your browser cache
@mwav3 this is how my configuration looks like.
The “ssl: false” don’t seem to have any impacted!
Do the order of the lines matter?
Tried to clean the browers cache, no different 
Maybe the “502 Bad Gateway” error I receives after awhile when I try to open the UI is something ?
I don’t know why I haven’t checked the logger before!
But when I try to open NodeRed UI I receive following error
ERROR (MainThread) [supervisor.api.ingress] Ingress error: Cannot connect to host 172.30.32.1:64305 ssl:default [Connect call failed ('172.30.32.1', 64305)]
Anybody that know something about that?
I’m not sure if order matters but your config looks a little different then the example one, you can try and format the config more like the documentation example here:
That documentation also notes specifically under known issues and limitations:
If you cannot access HTTP nodes or Node-RED Dashboard, please check if you have enabled direct access mode by setting a port number in “Network” configuration section of the add-on.
If you cannot access HTTP nodes or Node-RED Dashboard, please check if you URL starts with /endpoint/, or else Home Assistant authentication will kick in.
Based on the advice above, try removing the port number on the network configuration tab to disable the “direct access” and only access the dashboard through Home Assistant ingress (ie just the Node Red tab in Home Assistant).
You also can try the config this poster suggested
I wish I had a better answer that I knew would fix this for you, but I just run Node Red in docker and not the addon, so I’m not familiar with all the quirks and finer details of getting the addon to work other then what we’ve tried. Unlike a traditional Node Red install (ie docker, snap, NPM) that just runs on port 1880, the Node Red addon appears to route the connection to the supervisor and all over the place through a bunch of different ports and uses ingress so a lot can go wrong. Hopefully someone else can chime in if they have any other ideas.
If all else fails you can just give up on the addon and run Node Red directly on port 1880 outside of Home Assistant, instructions to do that are below
https://nodered.org/docs/getting-started/local
Instructions to get a traditional Node Red install (NOT an addon) working with Home Assistant are here
You also could attempt to open a github issue for the addon to possibly evaluate for a bug and get help from a developer
What error do you get when using direct access in lieu of going through HA eg. Your HA address with :1880 rather than :8123 If your using https you will have to make a security exception in the browser to display the page.
Have you tried changing to a different port on the config page?
I wonder if the work around from an old HACS problem would help. Force disabling the cache for the page.
@Mikefila, I’m using https. How do I do the security exception?
Do I have to do an execption on each browser I’m using?
I.e I log on to the system from different computers.
I tried to remove the port (1880) as @mwav3 suggested. But no change 
When you go to the page in a browser there will be a warning there will also be a link or button that will give you further options. You can try another port like 9025 and then use that at the end of your ip instead of 8123
New discovery…
I can access Node Red UI with the ip-address:1880
But I can’t access the Node Red UI from the HA frontend (buttons, open web UI)
I have the same issue but I can open the nodered ui from HA on all my screens (pc, laptop and tablet after logging ) not on my iPhone. On my iPhone there is a black screen with the text “unautorised” ???
