vpncloud service fail to start because a timeout was exceeded

[leehui85]

Hi，

I executed the following commands on ubuntu 20.04，and met a timeout issue. Is this a bug?

wget https://github.com/dswd/vpncloud/releases/download/v2.2.0/vpncloud_2.2.0_amd64.deb
dpkg -i vpncloud_2.2.0_amd64.deb

create a test.net under /etc/vpncloud with below contents.
crypto:
   password: mysecret
ip: 10.127.0.1
peers:
  - x.x.x.x:3210               (x.x.x.x is a valid public ip)
  
  then, execute  "service start vpncloud@test", I got the folowing error messages.
  
  Job for [email protected] failed because a timeout was exceeded.
  See "systemctl status [email protected]" and "journalctl -xe" for details.
  
  journalctl -u vpncloud@test ,  show the following messages.
