My server ip: 112.78.8.161 ( add-on ip: 112.78.8.160 ) And you are running that rsync command from your mirror server, ie. from one of those IP addresses? There have been cases where the outbound connections are NATed to come from some other IP address. One fairly certain way (excluding proxy setups) is to run "curl ipv4.miuku.net". It should return the IP address that the remote end sees for your connection. If this differs from 112.78.8.160/161, the whitelist may need to be amended.
