JS UI update from 1.8.1 to 1.9.0 broke my integration

I got the dreaded “Retrying setup: Failed to connect: Cannot connect to host a0d7b954-zwavejs2mqtt:3000 ssl:default [Connect call failed (‘172.30.33.1’, 3000)]” error on the Z-Wave JS integration card. Clicking “Configure” on that card gave an error screen. I tried restoring the partial update that was automatically created right before the update, but this gave the same error (I think because I hadn’t rebooted after the restore?). Then I restored the full backup that had been made just a few hours prior to the update. This took 15 minutes, then after a reboot everything Z-Wave was back to functional. This was my first restoration, so I’m glad it worked. I only lost a single automation that I made last night, so not a big deal. I’m not sure if this is the place to post this, but this community has been pretty helpful in the past, so I figure I’ll get pointed to the right place if this isn’t it. I’m going to hold off on updating (there’s no ignore option, unfortunately) until this bug gets addressed.

I’d suggest looking at the add-on logs next time.
