Hi there!
It seems like our IPv6 is not whitelisted becouse we are geting the following error when we sync from eu-msync.centos.org::CentOS via IPv6. However it work just fine when we run it via IPv4.
@ERROR: Unknown module 'CentOS' rsync error: error starting client-server protocol (code 5) at main.c(1653) [Receiver=3.1.1]
Our mirror server is mirrors.glesys.net
Can you please add our IPs to the whitelist. IPv4 : (109.74.12.226) IPv6 : (2a02:750:9::e8)
Best regards. Abdulaziz Al Ahmad.
