Dashboard is not working anymore

Dashboard
1

Hi community,

First of all: sorry for my english…

i got a Problem with my Dashboard, after i finished programming some Nodes and adding their data to the Dashboard, i shut my raspberry down.
After i reboot it this morning again and wanted to check my Dashboard, it doesn t worked any longer.
There is always this message:
Welcome to the Node-RED Dashboard
Please add some UI nodes to your flow and redeploy.

but i already added some ui Dashboard notes…

could any one help my to fix this Problem?

It would be useful to see the log that Node-RED prints when you start it.

Also have you installed any other nodes that include the word “dashboard”? If you have these unfortunately stop the node-red-dashboard from working. You should delete them and then restart Node-RED

here is what node red prints:

Node-Red start

Start Node-RED

Once Node-RED has started, point a browser at http://192.168.1.44:1880
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.

i don t have any other nodes including the word Dashboard…

4

Do you need the following nodes that you have installed?

They are for use in Bluemix but you have it installed on a raspberry pi. Try deleting them and restarting node-red.

5

i already tried to delet them but node red says they are in use, what they defenetly aren t…

6

Unbenannt

7

So that suggests you are using the mongoldb nodes. If you are definitely not…

In a terminal
node-red-stop

cd ~/.node-red

and then

npm uninstall node-red-bluemix-nodes

then restart Node-RED

8

okay now the terminal says:

picture

Unbenannt

but i defenitly had no node in my flow which is called mongoDB

9

If you look at the menubar in Node-RED there is a “Search flows” option and see if you can find it

Otherwise look at “Configuration nodes”

yes thank u i fix it now :slight_smile:

11

Which one was it? A node or a configuration node?

12

probably it was a configuration node which blocked my Dashboard ui. So i deleted all background nodes and stuff i don’t needed any more and now it works.
I hope it is still working tomorrow
