Hello, I have two TrueNAS systems on two different locations. Box 1 is backing up to box 2. Both run the latest Scale Cobia release and have been doing rsync as well as replication tasks via a SSH connection for a couple of years now.

However, when running the replication task, I now get the following error: [EACCES] PermissionError(13, 'Permission denied')
Rsync continues to run fine using the same SSH connection and SSH keypair.

While troubleshooting, I found that entering the current IP address instead of the DynDNS address into the TrueNAS URL field in the SSH Connection UI works. Entering the DynDNS address leads to the same error again.

Do you have any idea how to solve this?

I tried adding a new SSH connection, but it keeps showing the same permission error. It is also not able to discover the remote host key.
