Nextcloud Snap Says it is out of Space, But Drive Has Over 500GB Free

For some reason Nextcloud is telling me I am out of space with only 81GB of my files synced. I have Nextcloud installed on a 1TB hard drive with almost nothing else on it, so there is plenty of space. I even created a second user with unlimited storage and got a message that I was out of space the first time I tried to upload something. I have ~130GB total that I need backed up.

My Nextcloud instance is installed using the Snap using a bare metal install of Ubuntu Server 20.04. As far as I know, I used the default settings for everything.

I have pasted the output of df below:
