Error : remote installation does not seem to have a running Node Red service

Hi all, using a Cerbo GX.

I've been using Node Red for a couple of days, very new to it all, everything great, then I installed SQlite to run something that someone else had coded and my node red installation seems to be broken.

I am not familiar with any of the lower level commands etc of Venus/ Pi etc.

I reinstalled 'Normal' firmware and then 'Large' firmware again and it's not made any difference. Have rebooted the Cerbo. Just get the message above - 

Error: remote installation does not seem to have a running Node Red service.

Can anyone suggest what to do to bring back my Node-Red?!

Luckily, I have saved all my work!

Thanks

Mike

You can start Node-RED in safe mode and fix the problem. See https://www.victronenergy.com/live/venus-os:large#q5how_does_safe_mode_work_and_what_is_it.

Hello Mike

I have had the same problem for more than a week now, also trying the same steps to fix problem without success.

And no, starting Safe Mode does not help.

Any suggestions?

Regards, Otto

It is strange that it won't start in safe mode. The most invasive solution is to wipe everything from /data/home/nodered/.node-red/, but I don't believe that should be needed.

What error does safe mode give you?

Hi Dirk-Jan

Wiping the directory seems very invasive, and I am uncertain of the outcome.

Here is the error msg, which is the same no matter Safe mode or not:

Can you access it via your local LAN on https://venus.local:1881/ ?

No. Basically the same outcome (tried different browser also). And NodeRed is enabled in Settings, and not restarting.

Can you login to the device via ssh and check /var/log/node-red-venus/current ? that file should give the reason why it won't start.

It looks like the yr.log file permissions is the cause. Can it be that you installed the yr weather node? If so, I’ll test that myself too to check how to fix it.

Yes. I just did a test myself and installing yr.no weather node crashed VRM Node-Red again. Guess I'll find a different weather service :)

Out of experience I know that they are one of the best, especially when you get closer to Norway. But there are alternatives. I'll probably take a closer look at it tomorrow evening.

Problem lies in this line: https://github.com/tverilytt/NODE-Red/blob/fb07fc06bcdf90f0cc32389ede4d7b61782459b4/yr/yr.js#L26C40-L26C46. Changing that to '/tmp/yr.no' (in '/data/home/nodered/.node-red/node_modules/node-red-contrib-yr/yr.js') helps a bit, but then it starts complaining about a missing 'haversine-distance'. Which can be installed from the commandline (`cd /data/home/node-red; npm install haversine-distance'; don't forget to do a `chown -R nodered:nodered /data/home/nodered` afterwards as you don't want the files to be owned by root). And then restart Node-RED.


Probably a better solution: use another weather node.

After further research I decided for a remove & re-install, and Node-Red is up and running again

This worked:

  1. Keep Large OS enabled
  2. Log in as root via SSH
  3. Remove Node-Red by running the following code:
  4. rm -rf /data/home/nodered/ && svc -t /service/node-red-venus/
  5. Install Normal image via Remote Console
  6. Install Large image via Remote Console
  7. Open Node-Red :)

Thx for all help!

I suddenly have the same problem "NodeRed service is not running". I followed above steps but this does not help.

  1. Keep Large OS enabled
  2. Log in as root via SSH
  3. Remove Node-Red by running the following code:
  4.                     
      
                     
    1. rm -rf /data/home/nodered/ && svc -t /service/node-red-venus/
      2.
  5. Install Normal image via Remote Console
  6. Install Large image via Remote Console
  7. Open Node-Red :)

Via https://vrm.victronenergy.com/installation/....... I go to my setup and normally use the menu option 'Venus OS Large' to go the node-red environment but that screen remains empty except above error message.

Via https://venus.local:1881/ I can still go the NodeRed environment and import my flows again but all UI nodes are unknown. On the other hand the Victron nodes appear to be ok.

I have not installed extra nodes or made any other changes, I am just using the Victron OS-large as-is. In fact this is the first time I logged in using ssh to do above. As part of the above I upgraded Cerbo-S GX to v3.12.

What could be wrong here and what can I do to resolve this?

This seems to be an issue when accessing Node-RED via vrm. When I try to access Node-RED from a local network or from betavrm.victronenergy.com then it works.

Same situation here since 10pm on the 13th november. Impossible to acces to Node Red throught the VRM.

Something has changed since this morning. I can access node-red via VRM again. The first time I got a message about a certificate. Unfortunately I tried to understand this first before I accepted because when I finally did accept it said the certificate had expired. I did not get the notification anymore on later invocations.

The VRM screen only offers the option to go to node-red, not the option anymore to go to the node-red-UI.

In node-red there are no UI nodes.

I start to believe the expired certificate is the reason things suddenly do not work anymore but I do not understand how this works. Any suggestions?

Found it. I need to reinstall node-red-dashboard in node-red. Only problem left was after importing my flow again that these UI nodes are somehow not associated with the nodes in my flow anymore. Reassigning them to a dashboard group fixed that. Pity that save-restore of a flow does not work completely.

I was happy too early. After deploying my flow this message pops up in the debug output window. now what?

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.
