So I installed Openhab3 on my Raspi 4 and after a few minutes you can connect via "http://openhabian:8080" to the system.
It's working on windows (with chrome) but not with my Ubuntu system (Firefox). Both is set up to the same network system. Both automatic dhcp.
I can ping the raspi and it's fully responding. But, as mentioned, it is not possible to get access via Browser. So it's not really possible to set up the system as I want to do it. Yes windows is possible but my everyday usage is on ubuntu.
How can I get it to work? I guess there is something wrong with the network preferences.
Thanks for the help.
My system: I'm currently on ubuntu studio 21.10
