First of all, thanks so much for your warm welcome, and your fast answer.
Again thanks
I fixed the problem, it was from firewall site. Rules were blocking 443 and 80 ports.
Duplicati is installed in NAS Asustore with portainer, everything were great in LAN but as OVH in on WAN it’s was blocked.
that said, Duplicati works like a charm with OVH, and I backuped and restored file with out problem.
I spent hours and hours on configuration stack for accessing to folder from container, basically because Asustore ADM “put” files in “User Homes” by default, which is bindded in the NAS, I have to move files to other directories to mount them in Portainer for Duplicati access.
Here’s the file, it would help maye others
”version: “2.1”
services:
duplicati:
image: lscr.io/linuxserver/duplicati:latest
container_name: duplicati
environment:
