I went on a head and tried different things now I am getting this error.

This is what I get when I do that command.

[16:55 xcp-ng-MainServer ~]# showmount -e 192.168.1.1
Export list for 192.168.1.1:
/mnt/LocalStorage/XCP_NG_Backups 192.168.2.0
/mnt/LocalStorage/XCP_NG         (everyone)

I tried adding a NAS for my delta backups but apparently it refuses to connect when adding it as a remote connection.

This is the error I receive:
"Command failed with exit code 32: mount -o vers=3 -t nfs 192.168.1.1:/mnt/LocalStorage/XCP_NG_Backups /run/xo-server/mounts/5edaab67-b6c6-4a39-9294-e30920b065d2 mount.nfs: Connection timed out"

Storage server is running TrueNAS.
