Can't find the request for http://192.168.x.x:8080/rest/events's Observer

After running into lots of troubles when migrating my OH3 installation (Caspian, OH3, Java 11) to OH4, I decided to start from scratch with openHABian and OH 4.0.1 - all fresh, all new, should work like charm.

  • openHABian installationwent fine
  • I used openhabian-config to make adjustments and install option components
  • I selected only 2 basic bundles, even not basic-ui
  • look good UI started

Then I restored the migrated OH config (from OH 4.0.1). which seems to be completed successful
BUT NOW when starting OH I see a lot of those errors:

I can confirm what @Wolfgang_S say. There is a browser open with Openhab UI that try to access the data. At boot the web server isn’t ready to response and you get exactly this in your logs.
That’s all.

Yip. I also see that sometimes if there is a web client trying to connect during startup of openHAB.

The only solution I have found is to close all the web clients and restart.

Hmm, never saw this, but who knows…

I decided to start over once more. I want to make sure to have a clean base install, this needs to stay for the next 5 years with OH :slight_smile:

Thanks for the quick responses +1
