Looks like this is a permissions issue. Disabling SELinux seems to resolve this issue (there are plenty of discussion about SELinux) or perhaps just changing the permissions on /proc/sys/net/ipv4/ping_group_range
sudo chmod 777 /proc/sys/net/ipv4/ping_group_range or similar might do the trick.
I am not able to reproduce on my side, but let’s see where that gets us.
