It isn't added. It's possible I was missing a step there.
I'm going ahead and closing since it is probably related to something there but we removed replication from VCP so it's not necessary any more.
Sorry, but is generated key added to vcptesting3.lab.ixsystems.net? I've tried to log in with the key you've posted and it was not accepted.
First I call "keychaincredential/generate_ssh_key_pair", which for instance creates what I put in the attribute for "/keychaincredential":
{"name":"vcenter_sshkey_vcenter_replication_tank/testvmfs75_1605639156433","type":"SSH_KEY_PAIR","attributes\":{"private_key":"----BEGIN OPENSSH PRIVATE KEY----

I then invoke "/keychaincredential/remote_ssh_host_key_scan" with {"host":"vcptesting3.lab.ixsystems.net'} and use the output to create an SSHConnection with {"host":"vcptesting3.lab.ixsystems.net", "port":22, "username":"root", "private_key":1, "remote_host_key":"ssh-ed25519 AAAAC3NzaC1lZDI1NTE5AAAAIARjkGdcmbELKEaM0LEN/5oYBLdw+/ZyKkpthW3/3Bj8","cipher":"STANDARD","connect_timeout":10}. Finally, I create the Replication task with "/replication:
{"enabled":true,"source_datasets":["tank/testvmfs75"],"target_dataset":"tank/repl","ssh_credentials":2,"name":"vcenter_replication_tank/testvmfs75_1605639156433","direction":"PUSH","transport":"SSH","auto":true,"retention_policy":"NONE","periodic_snapshot_tasks":[1],"recursive":false}
The SSH services on both systems are running as well.
@Zack I need your sequence of API calls please
The debug as well...

The vCenter plugin creates replication tasks using the API. It first generates a Key, creates an SSH Key Pair with that key, then creates an SSH Connection, the finally creates a Replication task with this connection. All API commands succeed and the task is sucessfully created, which can be validated by the UI. However, the task fails due to an authentication error as follows:
[2020/11/05 09:23:36] INFO [Thread-9] [zettarepl.paramiko.replication_task__task_6] Connected (version 2.0, client OpenSSH_8.3p1)
[2020/11/05 09:23:36] INFO [Thread-9] [zettarepl.paramiko.replication_task__task_6] Authentication (publickey) failed.
[2020/11/05 09:23:36] ERROR [replication_task__task_6] [zettarepl.replication.run] For task 'task_6' non-recoverable replication error ReplicationError('Authentication failed.')
A workaround is to create a new SSH Key Pair from the UI, then assign that key pair to the API generated SSH Connection. The task will succeed. Regenerating the SSH Key Pair created from the API will not work. Neither will rediscovering the public key for the connection and key pair.
Attached is the API call for a functional and non functional task/connection, the functional being copied from the one starting with "vcenter_".
