Hi, after migration from pi3 to pi4 everything works fine but the dashboard button in the editor opens a new tab in the chrome or safari browser and shows http://192.168.178.111:8123/endpoint/ui with response 404: not found. So no dashboard is shown. For a test, I deleted flows.json to get an empt…

[image] I found a solution!!! In home assistant press "factory reset" in Settings/addons/Nodered/configuration menu, then restart nodered and --- it works. Thank you for your wonderful support!!

[image] guenter-ms: The 404 not found message obviously occurs when NR tries to build the rest of the URL following /endpoint/ui/..... No, I don't think that's right. Everything after the /ui is not real. You can see that on a working system by looking at the network tab of your browser's dev…

I activated the developer tools in chrome browser and saw this: [Bildschirmfoto 2023-09-15 um 10.47.18] Maybe I have to look at another place (can you give me a hint?) Now I tried to append the /#!/0 manually to the url in the browser http://192.168.178.111:1880/endpoint/ui/#!/0 and then it wo…

There you are using port 1880, the one that failed showed a different port.

That is interesting!! It runs with port 1880 and http://192.168.178.111:1880/endpoint/ui So what's the reason for calling port 8123 which is Homeassistant? And how can I change that?

What port do you use for access to the editor?

I use http://192.168.178.111:8123/a0d7b954_nodered/ingress . NR is embedded in Homeassistant frame. Same on my working reference system (different IP) [Bildschirmfoto 2023-09-15 um 19.33.56]

[Bildschirmfoto 2023-09-16 um 14.44.28] I tried to find out, but the only thing I found is the lolentry concerning this ignored message: [Bildschirmfoto 2023-09-14 um 17.17.31] Any idea what that means?

I have exactly the same problem. I am using node-red v3.1 on Home Assistant HASSOS. Everything is the latest version. When I try to access the node-red dashboard, running under Home Assistant the URL is http://192.168.1.98:8123/endpoint/ui . Whereas if I type in http://192.168.1.98:1880/endpoint/…

Cannot open node-red-dashboard after migration from pi3 to pi4: 404 not found

Dashboard

I'm afraid that is a Home Assistant question.

The Node-RED question is whether or not the Editor shows port 8123 in a previous version and if not, what has changed? Can you check that?
