Rsync mess and needing some guidance

Hi folks, I’ve made a bit of a mess with trying to setup rsync. I have created rsync as an account but had issues with getting it working with my synology. I went ahead and created a second rsync user and called it rsync2.

I “think” I’ve managed to sort the ssh key but when I ssh to my synology it still prompts for the password, I’ve gone through and updated the authorized_keys on the synology.

When I run a ssh rsync task via Rsync Tasks, it eventually fails with the following:
[EFAULT] rsync command returned 12 - STREAMIO. Check logs for further information.
Error: ssh: connect to host 192.168.2.37 port 22: Connection timed out
rsync: connection unexpectedly closed (0 bytes received so far) [Receiver]
rsync error: error in rsync protocol data stream (code 12) at io.c(231) [Receiver=3.2.7]

With this in mind, the IP address for both Truenas and Synology have both changed, neither of these are .2.37 but I also can’t find where it is referring to this IP, I’ve checked the rsyncd app and removed it from the Hosts Allow, I then restarted the rsync service via systemctl restart rsync.service but it still fails with the same. Clearly, I’ve missed a location but am unsure where.

Lets start with software version, IP addresses and rsync task settings.

So software version I’m assuming is for Rsync in which case App version 1.0.2, Version 1.1.10

IP Address is as follows:
Truenas: 192.168.50.190
Synology: 192.168.50.50

Rsync task is configured as per screenshot:

which version of TrueNAS?

Sorry, I believe 24.10 but I’m not at home at the moment but can confirm tonight.

Yes it is ElectricEel-24.10.2. Would it be easier to do a manual rsync via the CLI?

Ok, so I deleted my rsync user from both synology and truenas, recreated and setup a new rysnc task via SSH and get the following when I attempt to run it:

rsync: [generator] failed to set times on “/mnt/storagepool/Nathan/Test/.”: Operation not permitted (1)
rsync: [generator] failed to set permissions on “/mnt/storagepool/Nathan/Test/@eaDir”: Operation not permitted (1)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1865) [generator=3.2.7]

The attributes set on the job are as follows with no auxilary parameters:
