maybe an issue?

I suspect the host Ethernet interface is not setup correctly

Can you post the results of the command:

ip a

Nice suggestion
I ingnored ipv6 and all well

this is the working ip a

2: enp3s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link/ether 30:5a:3a:53:48:4d brd ff:ff:ff:ff:ff:ff
inet 10.10.10.1/24 brd 10.10.10.255 scope global noprefixroute enp3s0
valid_lft forever preferred_lft forever
inet6 fe80::9779:1c84:5c46:75b8/64 scope link noprefixroute
