Truenas Core to ZFS on Linux mahcine replication failing

[hescominsoon]

i ahve created the ssh connection and discovery of the ssh key was completed successfully. When i try to add the remote system(which is proxmox ve 7.1.1) i get a big barfage window. The last line is middlewared.service_exception.CallError: [EACCES] AuthenticationException('Authentication failed.')

trying to figure out how authentication is failing. let me post he entire output:
Error: Traceback (most recent call last):

is the remote system rejecting the key? once i understand what all of this means it wil give me an idea of where to start looking..:)

so i can ssh from the freenas machine to the proxmox mahcine using root..so that's ok. Still trying to figure out what is not working between the two.
