Did an upgrade (core) this morning while I was at the gym, seemed fine, restarted, and I haven't been able to get in since.
I can get in via my local IP, but not through Nabu Cloud. Says loggen in but not connected, and the android app says there's a TLS certificate error, my SSL is good until August. This was all working fine until I installed the update this morning.
I tried reverting to a backup from yesterday, which doesn't actually roll it back. I hit restore, HA reboots, and I'm still on current when it comes back up. When I disconnect Cloud and re-enable it, for it'll say logged in and connected, and then quickly reverts to logged in and not connected.
Yup, both logged out/in and did the Reset cloud data in between. Now it says cloud is connected, but the remote access box below it says it's not connected, which is says connected at first, but then goes to that.
That's what I figured, an update that died in progress, I'm in it now but only locally direct to it's IP. Can't get at it from the .nabu or even through my duckdns, like something in it's network stacked died.
What's also confusing is I tried to revert it to a backup it made yesterday, but when I tell it to restore it, it acts like it does, then says it needs to reboot HA, that lasts for a few minutes but then starts back up and it's not reverting.
If you are using a device with an SD card, updates are by far the most likely time for the cards to fail, as there is a lot of new files written and files deleted…
I agree on the SD cards dying, but everything seems to still work fine locally when I access it direct by it's LAN IP.
One thing I noticed though is my Let's Encrypt integration is gone, I don't think that would affect it working through the cloud address, but weird as I never removed it. Also don't see it listed anymore if I try to add it, I had my local IP through SSL as well and that seems to be gone now. Something went stupidly wrong on this one!
