   Check /var/log/shadowvpn.log for what happened

5. general diagnose steps:

   1. on client ping server real IP
   2. on client ping server VPN IP 10.7.0.1
   3. on client traceroute 8.8.8.8 make sure it goes through 10.7.0.1
   4. on client ping 8.8.8.8; on server sudo tcpdump -i tun0 see if any packet arrives
   5. you can also run sudo tcpdump host 8.8.8.8 or sudo tcpdump port 53 etc on the client or server
