If the VPN is dropped then it will be logged, wait for the log to update.

Then it is not openvpn at fault.
Either your server is doing something to change it's network configuration or somebody outside is blocking you.

what could be the possible reason? as internet works fine right after connecting VPN, but after few minutes it stop working, but the VPN is connected.
Is there anything related to Encrption or something? or anything related to ISP?

You need IPforward and NAT at your server. at the moment it only can ping 10.8.0.1 only.
open terminal and type
sudo su
/proc/sys/net/ipv4/ip_forward =1
this make IPforward then
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
this is NAT so client can find the way get out to internet.

You need look at log to see what happened after connected. Something is wrong so it stop working. Without log nobody know why.

Because it is not openvpn going wrong, it is either his server or ISP doing the block.

I know this log does not show anything, but the situation is it does not disconenct the VPN, it only stopped me to access internet. i can only ping the Main IP of server on which i conencted the VPN, i cannot even ping the VPN gateway IP 10.8.0.1
