ZFS Replication to Proxmox Backup Server

[flamelcadet]

Hello, I am trying to set up replication to the proxmox server, but I ran into a problem:
I create a bunch of ssh keys on the proxmox server, insert the public key into TrueNas gui->, SSH Keypair, then add SSH Connection and get the Remote Host Key
And when I try to create a replication job, I get an error:

Code:

What am I doing wrong?
I also tried adding the private and public keys of the proxmox server to TrueNas, but then I get an authorization error

You can close the topic, set everything up via SSH without NETCAT

Can you please detail what exactly you did?

I am trying to set up zfs replication between my TrueNAS and Proxmox servers and I am getting the same error as your first post. Were you able to set up the ZFS Replication between TrueNAS and Proxmox? How did you achieve it?
