Upgrade from Z-wave JS 0.1.45 to 0.1.47

Updated Z-wave JS from 0.1.45 to 0.1.47, taking a partial backup in the process. After the upgrade is completed and the system rebooted, the integration is giving an error and none of my z-wave entities are available.

This is the error:

Cannot connect to host core-zwave-js:3000 ssl:default [Connect call failed ('', 3000)]

I tried performing a partial restore to 0.1.45 and the error persisted. I’m not seeing any errors in the Add-On’s logs either. Any suggestions of where to look next?

I’m running home assistant os on a rpi4.
Core: core-2021.11.2
Supervisor: supervisor-2021.10.8
OS: Home Assistant OS 6.6

Had this problem on the ZWaveJS2MQTT, too. Maybe the same problem on both integrations.

I resolved it by switching the USB-Port to a false one (don’t miss to save) and then back to the correct one. Since then even after several reboots ZWaveJS2MQTT is still conected as before.

Okay, I’ll give that a try.
