Updete from 2.4 to 2.5 error


I updete my openHAB, and after that this happend:

The basic ui disappear and apear again after several seconds. The IOS app drops error (Response satus code was unacceptable: 503)

Can somebody help me? Thanks!


Have you watched the startup log after the upgrade for any errors/issues?

Often two or more full startups are needed after an upgrade. If 2-3 full restarts of OH, without any issues in the log remaining, still won’t help, you might want to clear the cache and restart.

All the best.

Ok, I try reboot it.
How can I clear the cache?

You should checkout past posts about addons.cfg entries, in particular about REST API location.

Best to






Stop openHAB : sudo systemctl stop openhab2.service
Clear cache: sudo openhab-cli clean-cache
Start openHAB again: sudo systemctl start openhab2.service
