Vaultwarden with individual paths settings - no access to web interface

Following behaviour:

Deployed Vaultwarden with individual paths(setup as generic) specifications(/mnt/VM_Docker/Test_Generic) for app and db - deployed successfully.
But I can’t access web-/admin interface.

When I deploy Vaultwarden according to iX path specifications(ixVolume (Dataset created automatically by the system)) I have full access to web-/admin interface…

…any idea?
