Hi There,
"
Split tunnel OFF" means that you will be redirecting all traffic via OpenVPN Cloud.
But it seems you have not configured any vpn egress on a network connector, it means your OpenVPN Cloud does not have access to internet.
That is why "
Split Tunnel OFF" is not available.
So you need to allow "vpn egress" via this network's connector to turn off split tunnel.
To enabled VPN Egress on you Network please check this guide we have:

For more information with OpenVPN Cloud Split tunnel configuration/setup. Check this link:
