Host registration Error in Default enviroment

Recently,I download RancherOS v1.0.1 and Rancher Stable version in my eviroment,no Internet access ,with Vmware vSphere two VM Host in LAN,like 192.168.1.100,192.168.1.101
when I Add Custom Host,and run the docker command,But No Host Add to Panel,Anyone who knows why?
Thanks!

I got logs from rancher/server :

Can you share the logs of the rancher-agent container on the host you added?

I checked the rancher agent logs,It looks like all Ok,I moved it to another PC in VM workstation enviroment,with Internet access,It works!I want to know if Internet is needed at registration?Thanks!
