Out of nowhere, device discovery stopped working

[rabejens]

I configured some lights and fiddled around with groups. Out of a sudden, all of my devices were shown as "offline". So I discarded them all in my Alexa app, removed all my groups (as it was before) and restarted a device discovery. Still, no devices are found.

When I look in the logs of the skill, I see that the devices are correctly queried and discovered, however they don't show up in the skill.

I tried it with Homekit

There is a similar issue here (#39), and there it is recommended to reinstall Openhab. Do I REALLY have to do this or is there another way?

EDIT: I somewhere had an error in my configuration, or there was a constellation that Alexa doesn't like. Since the configuration was bad anyway, I started from scratch (without reinstalling, just deleted all my configuration files, and started with a simple .items file containing just one item) and it works again.
