I've configured Transmission to download to an external volume, (mount type: SSHFS but also tried CIFS): "download-dir": "/media/sshfs/downloads/",

I'm not sure exactly at what layer is the issue:

• my cloudron server is hosted at time4VPS
• the mounted volume is at Hetzner

I suspect that the SSHFS mount doesn't work well with torrent but not sure, I initially mounted the Hetzner volume with CIFS but switched to SSHFS to see if it works better.

I tried with qbitorrent with default config (so no moving to mounted volume) and was able to seed. So I think ports are fine.

Any idea ?
