Log error: Could not create required directory '/config/.cache/qBittorrent/'

Hi, folks.

I’ve just downloaded linuxserver/qbittorrent:latest and configured it per the example. However, attempting to connect to the webui on port 8080 gives me a “connection was reset”, and checking the log I see
Could not create required directory '/config/.cache/qBittorrent/'
recurring every second.

The weird part is that I have /config mapped to /volume1/docker/qbittorrent/config on my host, and the container has successfully created other directories below it:
root@Tower:~# ls -al /volume1/docker/qbittorrent/config
total 0
dr-xr-xr-x+ 1 Torrents users 68 Aug 19 23:57 .
dr-xr-xr-x+ 1 Torrents users 30 Aug 19 22:27 ..
dr-xr-xr-x+ 1 Torrents users 0 Aug 19 23:56 data
dr-xr-xr-x+ 1 Torrents users 32 Aug 19 23:56 qBittorrent

Furthermore, even if I manually create and chown /volume1/docker/qbittorrent/config/.cache/qBittorrent/ and restart the container, I get the same error - it’s as if the error message is not reflecting the actual problem.

Any and all suggestions welcomed.

Thanks!
