Hi,
Please check your firewall if you do not have anything blocking traffic to your devices. Also, it could be that you're trying to push all the traffic through VPN and if it's not up and running successfully - it could fail to forward the traffic. I would suggest looking at the certificates and configure it again from the beginning so you would have a clean set-up.
Make sure you have a normal internet connection without the tunnel running and then try to set it up and look for issues.
