I updated to OH3 with my OH setup on Rpi4 and everything was working. Explicitly the Webinterface was reachable as before. For performance reasons with another Pi Setup I moved the SD Card to my Rpi3 as suggested here and restarted. Everything seems to be working (rules and switches work) except the Webinterface. When I call http://IPoftheOHsetup:8080 from another computer I get “connection cancelled” error. I tried to find the reason in the logs from http://IPoftheOHsetup:9001 but it seems to only show logs till the day of the update to OH3 and in the Karaf Konsole with
ssh -p 8101 openhab@localhost
log:tail
I see recent logs but nothing seems to be related to the webinterface.
Probably I am not reading the (correct) logs correctly but I am stuck. Any suggestions how to investigate to problem correctly, so I can solve it?
Thanks for your quick response. I hesitated to include the useless logs I found via the mentioned command and concluded the first step would be I get a hint which logs to post and how to get them.
But let me show you what I got so far with
ssh -p 8101 openhab@localhost
log:tail

I believe there are some OS kernel level differences in between those CPUs. As stated in the other thread, that is beyond the scope of the openHAB forum. Starting a new thread here does not change that fact.
Suggestions here would be:
Do not do that
If you want to move OH to the Pi 3, import a backup of OH on the Pi 4 to a different SD card on the Pi 3.
The only problem I am experiencing is with the Webinterface which is not reachable. Since the OH backup does not include my Z-Wave (RaZberry2) settings and devices I would appreciate not having to start from scratch, especially as everything except the Webinterface seems working. Nevertheless if I missed a way to backup Z-Wave settings and devices you might want to forward me to I will of course try again.
After following the recommendations by Bruce-Osborne above (installing from scratch and loading backup files) I learned that the Webinterface is first working fine and only after installing deConz Phoscon App it ist not reachable any more. Therefore I assume it is not a problem with Kernel Differences of the zwo Rpi’s I was using (since I did a fresh install and it was working first). It seems it is running on the same port (8080).
That’s why I came to the conclusion to change the pprot of deConz ans suggested here: Phoscon/deCONZ on openHABian
Unfortunately it seems even after restarting deConz somehow still runs on 8080 but not OH:
sudo lsof -i :8080
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
deCONZ 383 openhabian 12u IPv4 17334 0t0 TCP *:http-alt (LISTEN)
