Can't upload gcode files

File upload fails on attempting to upload. Works on a different instance, but not on this raspberry pi

What did you already try to solve it?
Flashed a completely new image, disabled a couple plugins that I thought might have caused the issue, tried multiple gcode files.
octoprint (1).log (129.9 KB)

Logs (syslog, dmesg, ... no logs, no support)

Additional information about your network (Hardware you are trying to connect to, hardware you are trying to connect from, router, access point, used operating systems, ...)
Trying to upload from Windows PC to Raspberry Pi 4 2GB. Works fine uploading to a completely different instance on a Raspberry Pi 2B.

I also can't upgrade to the newest version, but that's beside the point.

Quite possibly the SD card is full. Ssh in, or use a keyboard and monitor and do a df -h and post that here

It's a brand new image on a 16GB card. OctoPrint lists 11 GB available of 15 total.

But here's the results from the df-h too
pi@octopi:~ $ df -h

Update: It seems to be working again now. I don't know why and I don't know how lol, I just kind of let it sit for a while and everything seemed to work itself out. The update completed successfully and I can upload files.
