Failed to connect error message from Z-Wave JS Integration

I am receiving the following error message from Z-Wave JS. I’ve searched the archives and haven’t found this error. My Z-Wave (GE/Jasco) switches are operating correctly, as are my automations involving these switches. I am not using the IP address noted in the error message. I had set up to use the call noted in the error as “cannot connect to host”.

Failed to connect: Cannot connect to host core-zwave-js:3000 ssl:default [Connect call failed ('172.30.33.3', 3000)

I’ve updated to the latest HA OS, latest HA Core and latest Z-Wave JS, If I specify core-zwave-js:3000 for the Z-Wave communications, I receive the same error. I don’t see in the documentation that the IP call to port 3000 is a requirement. I tried that and it didn’t seem to eliminate the problem.

What is Z-Wave JS trying to tell me?

What a coincidence. This just happened to me as I upgraded to the latest HA OS and HA Core as well, and migrated to Z-Wave JS. It was working okay but suddenly started throwing this error after I restarted the addon.

What I ended up doing was reboot the host (I am using a RPi4) and it was all working again.

Thanks for your reply. I rebooted, as well, to no avail. The error does not clear. I’m running HA OS in a VM in VirtualBox on a Win10 host.

zwavejsmqtt connects using websocket.
172.30.33.3 is a docker IP. The addons are just docker containers which each have their own internal IP

I would guess that either the addon is not running or the IP for that addon has changed.

@tmpugh Thanks for the explanation. I have never run Zwave2mqtt… is it a requirement? If I load zwave2mqtt will the error clear? Everything ZWave that I do use seems to be working fine, except for this annoying error.

I mean zwavejs in your case

What integrations or addons are you using?
I thought issue is your Zwave not work based on error but maybe you have 2 of same integration running

Is the error repeating, or is there only one log entry? If you upgrade or restart the add-on while HA is running you will always see the error, it’s perfectly normal.

@tmjpugh I have only one copy of ZWaveJS running…? If that’s what you’re asking me…?

@freshcoast The error is does not recur, if that’s what you mean…? I don’t recall what sequence I used for the updates, but it’s certainly possible you’ve caught exactly what I did. The error did recur…I just don’t remember the start sequencer I used.

Thanks to both of you for your help.
