Can't read from repository

I’m using the linux GUI version.

Using existing NAS / NFS share as a repository (6TB Drive)

The NAS is running OMV 8/Debian 13. Working for all other machines on the network, including mobile devises, windows devices. This is NOT a share issue. All shares have been working fine for over a year or so.

Local machine is auto mounting the shares at boot via NFS. Can read/write to the (6TB) share from my local machine (Debian 13) with a normal (non root) user

The NAS is already running Kopia and using the repository successfully to back up the data stored on it to the separate internal 6TB drive.

When I try to use the repository from the local machine, I select the 6TB drive, enter the encryption password & click “connect”. It hangs on “Initializing Repository” forever. If I click “Show log”, the messages say “permission denied when ReadDir: (name of share)”

This machine & user has full read/write privileges of the repository (6TB drive)

Where do I start troubleshooting?

Thanks
