  1. What do you see in the browser when you try to view the dashboard?
  2. Does the editor work ok on that port?
  3. Open the Developer Console in your browser and refresh the page and see if any errors shown.
  4. Please stop node red and start it again in a terminal and copy/paste the output you get here.

The log says that you have error in some function. Search where it is and fix it first.
(don't know about the other tabs, but in this tab the function without name I'd suspect)

5

Also you are using an obsolete and unsupported (by node red) version of nodejs (13.14.0). It may not be the cause of the problem but you should use either 12.x or 14.x.

In future please copy/paste logs rather than screenshot if possible.

Hello HotNipi,

the error of the function because of initial for global variable (global.get("waktu") is undefind value) .its ok for my flow,because when i tried import in port 1880 in the same pc its working. and the other of group dasboard appear

Having done that you need to re-install node-red and also go into each .node red folder and run
npm rebuild

In future please copy/paste logs rather than screenshot if possible.

If that doesn't fix it then stop the node red that is running on the default port and run the one that fails, with and without the port specified. That will prove it is the port that is the problem.

[Edit] If still not working then do what I asked in the first post:

Hi Collin

i already instal nodejs 14.15.1 and export my project in port 1881 and npm rebuild .
but the result is the same

Did you try that? Stop the instance of node red running on the default port then start the failing one, using the same command line each time, but first on the default port then stop it, then try on the other port.

11

i did tried it but the result is the same..
and now i realize when i import my flow one by one, a few dasboard appear normaly and when i tried import flow with UI-table widget my dashboard become error again, also when i add new UI-table

is there any widget component can i use to replace UI-table ?

12

Have you installed the latest version of node-red-node-ui-table?

Edit: Also if you simply add a ui-table to the flow does it mess it up or is it something to do with the flow you are importing?

13

yes i instaled latest version 0.3.10 (2 month ago)

if i add fresh new ui table its working only for ui table, but the other widget not show ..
now i still working on it and i got this msg
""*** Order property not set. Please contact developer. ***" on debug window when i tried deploy my flow.
edit : this msg appear because i import example of ui-table (simple table)

but on port 1880 everything is normal

14

What other widget and where do they not show?

15

Please confirm that you have tried running the same flows file with and without the port specified. So use exactly the same command line on the same system with and without -p 1881

16

i run node-red reffer to Steve-MCL on Node red multiple instances

node-red -p 1881 -u c:/node-red-1881

17

sorry maybe i can explain with a screen shoot

this is i make new fresh node on node-red -p 1881 -u c:/node-red-1881
and i tried import UI-table example Richer Table and add my own button on the same UI-Group

Please always show the command you have used to start node-red when you post logs, otherwise it is impossible to know what is happening. I don't know what you think is not right about the logs you have posted, though you have not only asked for a different port, but have also specified a different user directory.

Perhaps there is a language problem, but I still don't think you have done what I have asked. You think there is a problem caused by the port number, to prove that you must run exactly the same command except for the -p option.

ok colin thanks for support and advice.

maybe i pending it right now.and use port 1880
