Z-Wave JS: Failed Setup

Hello,

I hope you people can help me. I have a Z-Wave.Me USB Stick with Firmware: 5.39

Since yesterday the Z-Wave doesn’t work anymore. It states this message:
Failed setup, will retry: Failed to connect: Cannot connect to host core-zwave-js:3000 ssl:default [Connect call failed (‘172.30.33.1’, 3000)]

I looked over the Z-Wave JS addon configuration, it does use the correct USB-port, and the configuration seems correct.

Restarting en reloading the USB-stick and addon didn’t help. Also the reinstall of the plugin didn’t do anything

I also notice that the addon states in his logging:
s6-supervise zwave_js: warning: unable to spawn ./run (waiting 60 seconds): Exec format error

I’m running Home Assistant Core 2025.6.2 and Z-Wave JS Current version: 0.17.0
What information do I need to share so you can help me to let it work again?

Seems I solved my own problem. The uninstall & install procedure DID solve my problem after do it a second time…

Case closed

What exactly did you uninstall and reinstall? Just Z-Wave JS?
