Openvpn can access VPC but internet traffic is lost

I am creating a VPN to access a VPC, but I want the rest of the traffic to not pass through the vpn.

I've been able to access the VPC throught the VPN, but when connected to it, I loss access to internet.

This is my server configuration:

port 1194
proto udp
dev tun
ca /etc/openvpn/server/ca.crt
cert /etc/openvpn/server/vpn.crt
key /etc/openvpn/server/vpn.key 
dh /etc/openvpn/server/dh.pem
topology subnet
server 172.16.0.0 255.255.255.0
ifconfig-pool-persist /var/log/openvpn/ipp.txt
push "route 10.0.0.0 255.255.0.0"
keepalive 10 120
tls-auth /etc/openvpn/server/ta.key 0
cipher AES-256-GCM
user nobody
group nogroup
persist-key
persist-tun
status /var/log/openvpn/openvpn-status.log
log-append  /var/log/openvpn/openvpn.log
verb 3
explicit-exit-notify 1
data-ciphers AES-256-GCM:AES-128-GCM:CHACHA20-POLY1305

I've added this iptable to the server to access the VPC:

sudo iptables -t nat -A POSTROUTING -s 172.16.0.0/24 -d 10.0.0.0/8 -j MASQUERADE

And this is my .ovpn file for the client:

client
dev tun
proto udp
remote XXXXXXXXXXXXX 1194
resolv-retry infinite
nobind
persist-key
persist-tun
cipher AES-256-GCM
data-ciphers AES-256-GCM:AES-128-GCM:CHACHA20-POLY1305
verb 3
ca [inline]
cert [inline]
key [inline]
tls-auth [inline] 1
pull
<ca>....

When connected to the VPN, a route is added in the client with destination 0.0.0.0 and gateway the vpn server, I think this is the problem, but I don't know how to avoid this to happen.

~ route -n

I am using the default ubuntu network manager to import the .ovpn file and connect to the vpn.
