FreeNAS 11.3-U3.1 - SSH connection is ok but in Replication Task page not working as expected.

[thepiratebay]

Hi everyone. I made a fresh install on 2 device. Freenas 11.3-U3.1. Now i'm in trouble with the Replication Task between 2 Freenas devices. Main device and backup devices work in different locations. For backup devices network i made port forwarding for ssh. Ssh connection ok. But the destination location section on Replication Tasks screen gives this error. I try ''Advanced Replication Creation'' option but same here.''[EFAULT] AuthenticationException('Authentication failed.')'' error came up.
Please help me.
