I’m struggling too on a replication problem between my main nas… i can’t help you specifically on your situation but i have made a lots of test trying to solve… maybe there is something you don’t have already try and hope can solve, like:
- check generated/assigned Authorized Keys,
SSH password login enabled,Allow all sudo commands,Allow all sudo commands with no passwordon root account (for both system) btw you don’t use the truenas_admin user? you should - save the public key of each admin/root user into the other machine, under Backup Credentials → SSH keypars
- check SSH settings on both machine
- check SSL certificate
- try set a new ssh connection from Credentials → Backup Credentials, nor with ip and hostname
- try nor push and pull replication
