Cannot add z-wave device

To start: everything works fine.

But I cannot add a new z-wave device the blue add device button just does nothing. Both in integrations page as well devices (right bottom).

I have rebooted, restarted, pulled the zwave plug from the ZWA-2.

Multiple browsers, via the companion app… all same behavior…

What can be wrong?

activation fails

Which Add-On are you using? You should only have one Add-On related to z-wave installed. Try re-starting the z-wave Add-On. If that doesn’t work, delete the Add-On and reinstall it.

Zwave JS. Obviously only 1 is installed. I have restarted, rebooted, etc… its just so weird it does nothing…

You restarted what? HA or the add-on or both?
Have you tried uninstalling/reinstalling the add-on?

Everything you can think of…

try an incognito browser. And what versions are in use of HA, addon, HAOS , anything

I tried already… multiple browsers and same behavior in app…

All versions are latest (not beta)
