I have a selfhosted nextcloud on a proxmox box separate to my opnsense box but still internal. I have a FQDN for external and use split brain DNS for internal access. Both point to my opnsense box for caddy which then reverse proxies to the NC AIO LXC. Works fine everywhere except when trying to connect the backup to it. I've followed the official documentation: on the correct user, I created an app password and used that instead of my actual password. I'm constantly met with "Saved settings, but remote backup returned no files."
System > Logs > General shows various errors:
`Error while fetching filelist from Nextcloud '/.' path`
`Check Nextcloud configuration parameters`
For now I'm just backing up manually but I'd rather just have automated backups.
