Seafile photo sync not working

I have an android phone, app version 2.2.13 download from the play store.
Seafile is running through docker, I’m on my home network, and I can view the files hosted through the seafile app on my phone.
I’ve set up the sync functionality through the app, and enabled syncing through the android -> settings -> accounts -> seafile -> enable syncing. Camera upload is turned on in seafile app.
However I just get the error message ‘upload failed’.

Is there any logs or anything I can post to help troubleshoot this?

Can you upload anything from your phone?

Just tried it, and manually uploading doesn’t work either: ‘upload failed’
