Trying to rsync files into linode suddenly stopped working

We use Rsync to copy files in our ci to the linode machine. A few days ago the command stopped working

this is the command we are trying to run through github actions:

Run burnett01/rsync-deployments@4.1

##[debug]Docker Action run completed with exit code 255
##[debug]Finishing: Deploy to Linode

The command fails after roughly 17min and with code 255. I have checked /var/log/auth.log but could not find any log explaining why this would fail.

I see this: Warning: Permanently added '***' (ECDSA) to the list of known hosts..

So I assume the ssh connection is successful? How can I debug this?

EDIT

After more logs I see the process exit on code 12
