Remote server certificate not working when using RSYNC.

I am trying to rebuild my file server after the latest OMV update hosed the server. After setting everything up and trying to test, I received the following when I tried to run an Rsync backup to a remote server:

Please wait, syncing </srv/dev-disk-by-uuid-1fc0271b-686e-476b-a9e9-bfe91ef0e60c/Quicken/> to <xxxxx@192.168.1.xxx:/media/xxxxx/Backups/QuickenBKUP> ...

Permission denied, please try again.

Permission denied, please try again.

scans@192.168.1.135: Permission denied (publickey,password).

rsync: connection unexpectedly closed (0 bytes received so far) [sender]

rsync error: unexplained error (code 255) at io.c(232) [sender=3.2.7]

ERROR: The synchronisation failed.

END OF LINE

The certificate was installed via OMV, and I verified that the .ssh/authorized_keys was created.

I was going to rebuild the server anyway to use an SSD instead of an SD for booting. I have followed the official directions in setting up OMV and have never had an issue, so maybe there was an issue with the SD I was using that caused the server to go out to lunch. The new server is up and working great, but I can't get the backups to run again.

I just checked, and the certificates are the same on both servers.

Never mind, I'm just having my backup server pull from the OMV server.
