Wireguard Double VPN, Triple VPN. How to set up correctly?

Question

VPN

Good day gentlemen. I recently found out that there is Wireguard, read a little information about it, subtracted all the advantages of this VPN and I liked it, and it suits my tasks, and in my tasks the priority is ping and no packet loss. Since I don’t have much experience in self-configuration, and I didn’t come across self-configuring VPN so often, I found this article How to set up your Double VPN, Triple VPN - detailed ... it tells how to quickly set up all this stuff , a configuration script from GitHub is also attached, for a chain of such VPNs from 1 to 9 servers in the GitHub DoubleVPN stack I bought 3 VPS from different hosts, I did everything according to the instructions, but the miracle did not happen, when I connected there was no Internet and ping to the servers too, I tried to figure it out on my own, changed systems, tried it on Ubuntu 16,18,20, Debian 9.10, but not which did not work out, the problem remained, I started to climb on the servers to look for configs to understand what the problem was, and then I found the reason. The configs that the script should create are missing in the /etc/wireguard folder on all servers is empty. I tried to configure it manually, but it’s hard for me, iptables configs and understanding of the work of 3 subnets are not so easy for me. Guys help in solving this problem, let's make a working product for dummies as it was intended, in simplicity and 5 minute deployment of a large chain of encrypted traffic, if there is such a like-minded person, I am ready to provide you with a server and everything that is required, we will make a working product for everyone who is looking for an easy solution for their VPN server. I really hope to find you my friend!
