Hi JJK, I tried lowering the 'ping' rate from 10 seconds to e.g. 5

You said
"This happens most often when a bad switch is used that is not able to
handle UDP traffic or if a firewall is blocking traffic."
So tried following
1. Stopped OpenVPN server
2. on server nc -l -u 1194
3. on client nc -u 10.1.2.12 1194
From above, I can communicate using UDP protocol from client to server
in the same network. So does that means my network can handle UDP
traffic ??
your network was already capable of setting up a UDP connection -
otherwise the log files would not have shown anything. What remains to
be seen is whether your network can *sustain* a UDP connection. Start
your 'nc' example , let it sit for 3 minutes and then type something on
either end.
I have also uploaded client-server logs with timestamp sync.

your config files look perfectly fine, BTW. And the log files show that
both ends were able to read & write data - but for some reason the
connection was reset anyways... I'm puzzled. I'm kinda hoping that the
"nc+delay" test will show that there's a bad switch or router involved,
otherwise I'm out of ideas.

careful examination of the log files shows that communications
between the client and server break down after the initial
connect. In the server log you can find
WWWWRRWWWWWWWWWWWWWWWWWWWWWWWWWWThu Aug 25 11:50:45 2016 us=366024
pi2/10.1.2.14:42992 <http://10.1.2.14:42992> [pi2] Inactivity
timeout (--ping-restart), restarting
which shows that the server is writing packets (W) but not
receiving any (R or r) - which eventually triggers the restart.
This happens most often when a bad switch is used that is not able
to handle UDP traffic or if a firewall is blocking traffic.
If you have no control over the firewall or switches you could try
lowering the 'ping' rate from 10 seconds to e.g. 5 seconds using
keepalive 5 120

PS the timestamps are completely off when comparing the server and
the client log - it is best to keep the clocks in sync. That makes
it much easier to debug things like this.

without config files and more log output it is impossible
to tell what is happening. Connect over UDP with the
client with verbosity set to 5 (--verb 5) and post
anonymized client *and* server side log files. Also,
check the server log for anything related to WARNING or
ERROR.
