Hi,

Since I update node-red, I'm not able to connect to revpi node. Connexion lost always. . Need I come back to a previous version?

Sometimes it works but the response time is very long.

Is it possible to have several server running in the same time? Because when I open a node, I see 3 times Connecting to WS Server wss://localhost:8000 openning

Thanks

Here after what I see when I start node-red

pi@RevPixxxxx:~ $ sudo systemctl start noderedrevpinodes-server
pi@RevPixxxxx:~ $ node-red-start

Start Node-RED

Once Node-RED has started, point a browser at http://xx.xxx.xx.xxx:1880
On Pi Node-RED works better with the Firefox or Chrome browser

Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot

To find more nodes and example flows - go to http://flows.nodered.org

Starting as a systemd service.
Started Node-RED graphical event wiring tool.

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.

Hello,
I would recommend you to update Node-RED. There is a post in the forum about it:
