HELP PLEASE - Dashboard not working seem to have lost everything

Dashboard
1

Hello everybody,

For some reason, I’ve lost my Node-RED dashboard display (not dashboard 2).

I’m using the original dashboard, and when I click on my dashboard link all I see is:

“Welcome to the Node-RED Dashboard
Please add some UI nodes to your flow and redeploy”

However, my tabs contain charts and gauges, and I’ve checked the flows — everything appears to be configured correctly. I can also open the Layout Editor and all the UI elements are there exactly as they should be.

I’ve verified that the server IP address hasn’t changed, and everything looks fine from that perspective, but I still can’t get the dashboard to display.

Has anyone seen this before or have any ideas on what might be causing it?

Thanks in advance.

OK, please start by looking in the dev tools console in your browser and reporting on any errors.

Then also check the Node-RED log and also report not only any errors/warnings but also the startup where you see what versions of everything you are running.

Hi Shaun,

Highly improbable. Please stay calm and follow the instructions. Support here will help you out.

Hi I have ran the Dev Tools and here's what I'm getting back.
**Failed to load resource: the server responded with a status of 404 (Not Found)Understand this error
**Connecting to 'http://127.0.0.1:1880/.well-known/appspecific/com.chrome.devtools.json' violates the following Content Security Policy directive: "default-src 'none'". The request has been blocked. Note that 'connect-src' was not explicitly set, so 'default-src' is used as a fallback.

That isn't an error as such, it is expected behaviour. It can be ignored.

Hi All,

I found the error with the help of Chat GPT and Totally Information, I checked DEV Tool first as advised and they gave me some errors, I put these into Chat GPT and that gave me some things to try, didnt work but as we got deeper to find the root cause GPT then asked on the Node-RED CMD check for errors. below is an error:

"14 Jan 14:12:31 - [info] Starting flows 14 Jan 14:12:31 - [info] [ui-base:My Dashboard] Node-RED Dashboard 2.0 (v1.29.0) started at /dashboard 14 Jan 14:12:31 - [info] [ui-base:My Dashboard] Created socket.io server bound to Node-RED port at path /dashboard/socket.io Error: Circular config node dependency detected: 169c76c2995298dc at Flow.start (C:\Users\SMART IIOT"
I took the ID above and searched and found a group was unassigned, to be honest there was a few unassigned, so I deleted these then restarted Node Red and it works again .

Then you took @TotallyInformation 2nd suggestion...

Then also check the Node-RED log

These are the two most important 'Rules' when finding that you have problems with your Dashboard, or any other 'non-working' Node-RED error. They save a lot of time and if you are not sure what the errors mean, there is always a wealth of information available from the Forum and it's Members!!

Glad it is fixed.
