Client data - list of nodes empty

Hello all.
So I am working on the multi tenancy at flow fuse DB2. After viewing some videos, every people have under the description Accept client data some of nodes, but in my DB2, as you see bellow, is empty list :

Could you please tell me, why ?? What is wrong ? I have tried to restart NR, also whore RPi and nothing has changed.
Thanks a lot.

Are you viewing this on the RPI in its built in browser?

Check what version your browser is at - might be too old (may be errors in the dev tools console on your browser)

Also, try a different browser on another computer (access the RPi by IP or hostname)

@Steve-Mcl no, I am using PC browser, I have checked it on Chrome, and on FF, but still the same. Also I have new installed next RPi on another IP address with last version NR and node.js and after installing user-addon from flowfuse is everything same. Nothing differences.
Is there a problem, that it is local installation ?? I have not used cloud.

Do you see any errors in the browser dev tools console?

Are you using latest version of dashboard and node-red?

Dear Steve, I wrote, that I have also another new installation.
So there I have full new NR and Dashboard and newly installed DB2.

And also is the same. Nothinkg is displayed bellow the Accept client data.
Tested on 5 NTBs. In different explorers (edge, ff, chrome and also chromium at the RPi).
I do not know, what is wrong.

You haven't told us whether there are any errors in the browser developer tools console.

Also worth showing us the node-red startup log. Assuming that you used the convetional install technique then you can get that using

node-red-stop
node-red-start

Note the dashes in the command, not spaces.

@Colin so please check it bellow (I don't know, what you especially searching for):

and also starting NR :

If you need to see any details, please, feel free to obtain me. Thanks.

So, you are not running latest node-red (4.1.4 is latest) and not running latest dashboard (1.30.2 is latest) also, there are a whole lot more logs than you show (scroll bar) but most importantly is the 401 error on settings. Have you enabled security but not logged in?

@Steve-Mcl NR was installed three quarters year back. So I am not able to see every time updates. Is possible to reinstall it to newer, but I am not sure, if this solve the problem.
About your last question ..... so sorry, I don't know, what you mean .... enabled security and not logged in ??

I have installed the addon with the latest node red and dashboard and do not see your problem, so I suggest you start by upgrading.

In .node-red/settings.js have you enable security so that you need to login to the editor? In the file search for adminAuth and see if it is enabled. Also check the other settings in the Security section.
