Casaos : Running Syncthing on Casaos (Zimaboard) with an attached ESATA drive.

[IC-Water]

The drive is mounted (or at least I think it is) correctly, shows up in /mnt/External-1/ and works with JellyFin installed on same system.
The folder path permission is currently

/mnt/External-1
drwxrwxrwx 2 casaos casaos 4096 Mar 4 12:50 RemoteShare

When I go into the app setting within Casaos and add (same process I did for JellyFin) the following:

Volume
Host /mnt/External-1/RemoteShare
Container /RemoteShare [some posts suggest I change this to /Data, this did not help]

Docker restarts without error.

Go into Syncthing and create a new folder and point it to /mnt/External-1/RemoteShare, save it and get following error.

2024-03-04 17:02:28: Failed to create folder root directory mkdir /mnt/External-1: permission denied

2024-03-04 17:02:28: Error on folder "RemoteShare" (RemoteShare): folder path missing.

From what I can figure out reading other posts, this is a permission error - What is confusing is that I have a "Movie" folder with the exact same permission set as RemoteShare and JellyFin can access it just fine.

I have since tried this with Resilio and I have the same permission issues - so I am definitely doing something wrong.. :(
Any help is much appreciated.

Completely removed Syncthing, reconfigured with the same path for host and container and the folder was successfully added.
This is resolved.
