Lost power and now and I can't get Umbrel running

I lost power for about 12 hours the other day and haven’t been able to get my Umbrel back online since. The red light on the pi stays solid and the green light occasionally blinks, but the network doesn’t see it, so I can’t ping it or ssh in.

Any tips or ideas? If I import the keys into BlueWallet, will it force close the channels (eventually) and recover all of the funds, or just on-chain funds?

Any help would be greatly appreciated. Thanks in advance!

Update! I reflashed the SD card, put it back in, booted it up, and was able to get to a screen telling me that it couldn’t find the SSD. Unplugged that, plugged it back in, then rebooted through a link on the “can’t find the SSD” page. Booted back up just fine, took my password, and is just finishing syncing back up the chain. I’ll know once that’s done what the status of my lightning channels are.
