Can't create mount on Tdarr LXC (status=32)

[goaliedude3919]

I've installed multiple LXCs using tteck, including Plex, and never had any issues with mounting until now. I always follow the steps in this guide (although I don't use the uid and gid): https://www.geekbitzone.com/posts/2022/proxmox/plex-lxc/install-plex-in-proxmox-lxc/#Option1_Mounting_SMB-CIFS_Share

This has worked in three other LXCs with no problem, but I can't get it to work in my Tdarr LXC. I've even copied files directly from the working LXCs to the Tdarr LXC and it still fails.

This is the output from journalctl -xe
