Hello ckttkt,
Perhaps the 'power off' action was a bit rough, and it should actually be using a more graceful shutdown method?
In any case, try:
service openvpnas restart
If the system still doesn't come up, maybe a configuration you did earlier was incorrect and now the Access Server refuses to start because of that. You can examine the /var/log/openvpnas.log file for error message. If it contains anything sensitive please direct your question to our support ticket system at
https://openvpn.net/support instead of here.
Kind regards,
Johan
