Hi,

Look at this output on a newly installed Leap 15.2 system:

Notice how chronyd is trying to use IPv6 addresses, when my home doesn't have IPv6. The network is autoconfigured with DHCP (network manager) from the ISP provided and configured router.

carlos@Rescate:~> ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500

TX packets 32678 bytes 2686720 (2.5 MiB)

What should I look at? The system is with default configurations, installed hours ago.
