ah alrights, thank you!

@Eigenvektor that fixed it, thank you so much! assuming I have similar issues in the future, would a somewhat foolproof method to set the permissions to be owned by root, and then work on it from there?

auth.log shows this: fatal: bad ownership or modes for chroot directory component "/mnt/secondary/" it does seem like a permissions issue, though I'm not very sure as to how to fix it.

forgive me if this is the wrong place, somewhat of a newcomer here. I have a secondary PC acting as a server on Ubuntu 18.04 LTS. On it is a pi-hole, VPN, Plex, and a SFTP server. the pi-hole, VPN and Plex are working fine. the SFTP server is the problem. on this SFTP server, I have 3 users, all of which can only access specific folders which I assigned them. These folders are all on the primary drive, and all 3 of them works fine. I have a secondary drive, which is mounted at /mnt/secondary. When I try to setup a SFTP server which can only access a folder within the secondary drive, Filezilla throws me a "software caused connection abort" error. Full Filezilla log below.
