ping available with server but no ping with wireguard client

[egosha17]

Hi,
Installed Wireguard with auto-installation script of Angristan
Platform: Linode
Server: Ubuntu 20.04 LTS

What are possible reasons?
Server pings with my phone but no ping (10.66.66.2) over wireguard.
Location: Turkmenitan (ISP is good at blocking VPNs. They can even block OpenVPN)
So I want to practice Wireguard but could not accomplished yet.

I can't help but I'd recommend not sharing any of your keys :P
