Proper connectivity after fresh install.
zerotier-cli status shows "tunneled," but systemctl status zerotier-one shows "no route to host" and i'm unable to ping/ssh other members of network.
Ive installed multiple different os's trying to diagnose this issue and they have all had this same issue. Ive tried Tuxos, and Kubuntu both with the same issue, and tried installing through snap, the curl command, and compiling from source. Same issue. I dont have a firewall running.
