Dashboard disappears after a while

Dashboard
1

Hello,
I created a node-red dashboard on a Raspberry Pi 4, and it disappeared after a while.
I have recreated it several times, and each time it ends up disappearing
Do you have an explanation?
THANKS

@LauCaen Welcome to the forum!

With the information you have provided the answer is NO.

  1. How long does it take to disappear?
  2. Is the Pi connected to a monitor that you are seeing the dashboard on? or are you using another device to display the dashboard?
  3. Does anything else happen when the dashboard disappears?
  4. Are you running in a Docker image?
  5. What version of Node-RED and node.js are you running (you can find this in the startup log)
  6. since you can recreate it, can you provide the plow and the steps that cause it to disappear?

In order to make code readable and usable it is necessary to surround your code with three backticks (also known as a left quote or backquote ```)

Welcome to the forum @LauCaen

Also, when you say dashboard do you mean node-red-dashboard?
Do you mean the the flows for the dashboard disappear? If so do all your flows disappear or just the ones related to the dashboard?

How did you install node-red?

Have you got (or had) your node-red system accessible from the internet?

Hello,
All dashboards et flows disappear.
I installed with this process : Running on Raspberry Pi : Node-RED
Yes, it was accessible from the internet

Can you explain in more detail what if any security measures you put in place ?

You have been hacked. Any unprotected node-red accessible from the internet is likely to get hacked. There are bots out there looking for them. You will have to remove the port forwarding in your router, reformat the card and start again. See this FAQ post for advice on how to safely access node-red over the internet.

I've removed the port forwarding, and it is more stable.
Is it necessary to format card ?

Yes, you need to rebuild the SD card from scratch and don't import flows from the old one. You should also carefully check any systems on your network that the hacked system had access to as it might have spread an infection throughout, though we have not had any reports of infections spreading (yet).
