Failed to connect openvpn server

Failed to connect direct IP address openvpn server from micro router

If you enabled VPN but the VPN cannot connect to its server, there will be NO Internet.
When you change server while VPN is connected, VPN will not be leaked.

Internet connection is no problem without vpn
When I connect openvpn, Internet connection is lost

what is the log displayed on the openvpn connection page?

Here is my config file

tls-client
dev tun
proto udp
remote 192.168.0.1 1194
resolv-retry infinite
nobind
user nobody
group nogroup
persist-key
persist-tun
remote-cert-tls server
reneg-sec 0
tls-auth ta.key 1
cipher AES-256-CBC
comp-lzo
verb 3

I tried starting openvpn service cli mode
This is error message

root@GL-MT300N-V4:~# openvpn --config /etc/openvpn/client.conf
Options error: specify only one of --tls-server, --tls-client, or --secret

No failed from Linux openvpn client connect to same server
I think openwrt problem

Wrong config file.
But another problem. I will make thread another one
