common sense, client log (--verb 4), server log
There's a few typical problems
- network connection issues (firewall, NAT rules, server process not
running, server IP/port misconfigured in the client config) - this is
usually quite clear by not getting any response to connection attempts,
and not seeing anything in the server logs. Sometimes "ping", "traceroute"
etc. are helpful in figuring out where the packets are lost.
- TLS/auth issues, in which case the client *can* talk to the server, but
the server refuses to serve this client -> clear from the server logs
(and in newer OpenVPN versions, usually also visible in the client logs)
