perhaps this issue can be closed. I was able to fix it.

This issue happens when IPV6 is disabled following this CentOS7 specific instructions:

but IPV6 isn't disable in NetworkManager.

IMHO, the wiki entry that i have pointed above had better be modified, in order to add how to disable IPV6 in NetworkManager as well (In my case, i have disabled it in the /etc/sysconfig/network-scripts/ifcfg-ens32 file).

Hope this can be helpful for someone :)

Best regards,
