Nextcloud box reset itself after poweroutage

I recently had a poweroutage. And my Nextcloud Box (Raspberry Pi 3) decided to reset. When It came back online, it had me go through the first-time setup again after the power came back on for my Nextcloud box.

If you can help me get it to connect back to its original setup that would be great. If not, I will need to re-create all of that data. I’m better off using another service if the Nextcloud Box just resets itself during a poweroutage.

Hardware: Nextcloud Box (Raspberry Pi 3)
OS: Ubuntu Core 16
Nextcloud version: 11.0.5(stable)
PHP: 7.0.23

Your help is much appreciated!
