dh /etc/openvpn/keys/dh2048.pem
server 10.8.0.0 255.255.255.0
ifconfig-pool-persist /etc/openvpn/ipp.txt
push "route 192.160.1.0 255.255.255.0"

Hi People
It was my mistake, I did not follow the IP address rule for when using dev tun on window.

Please see below when execute "openvpn --show-valid-subnets"

Thanks!

============ result =========================
On Windows, point-to-point IP support (i.e. --dev tun)
is emulated by the TAP-Win32 driver. The major limitation
imposed by this approach is that the --ifconfig local and
remote endpoints must be part of the same 255.255.255.252
subnet. The following list shows examples of endpoint
pairs which satisfy this requirement. Only the final
component of the IP address pairs is at issue.

As an example, the following option would be correct:
--ifconfig 10.7.0.5 10.7.0.6 (on host A)
--ifconfig 10.7.0.6 10.7.0.5 (on host B)
because [5,6] is part of the below list.
