Founded fix for it :
its Working fine in Docker container binhex-urbackup , but in uroni/urbackup not working after bind mounted /etc/default to /mnt/user/appdata/urbackup/config/ and changed to “br0” Maybe some one fixed for Doker or how to check why config not used?
@uroni Is switching to binhex the recommended solution?
Fixed by setting custom docker network on eth1 + static Ip in Unraid
