The maintenance mode was to make my synced devices less angry about the constant errors. 
I don’t think the scan was the issue as it could see my files in nextcloud, I just couldn’t download them.
In a desperate attempt to fix was ever dammed mess I made, I did a backup and then restored to a new vm. That worked! Mostly… I am now having the issue that when I try to auto-upload from my android phone, I get an error that “Server not found,” and “Folder error.”
Manual uploads from the app, and automatic uploads from an iphone work fine. My attempts to “google” this issue have born no fruit.
