VPN not working how to find the cause?

For example now I took the server(scw), and immediately after his popular run run automatic configuration script
* https://github.com/Nyr/openvpn-install

In the end, the connection with the server is established but no Internet. Ubuntu 16.04 Client -> Server Ubuntu 16.04
Exactly the same settings from another provider work, and this one does not. Most likely the problem is in network settings, not the settings themselves, a VPN. There is a dump ipitables

Set up a normal guide describing all of the actions.

You have written in the rule - THIS_SERVER_IP_ADDRESS?
There is the IP of this server - Liza_Koelpin commented on March 12th 20 at 08:02
