Failed to initialize tunnel

[HOIMASAMI]

I'm using 1stRentalServer's VPS to install boringtun,
but when I'm going to run it, it got errors.

like this:
root@host:~# sudo boringtun-cli -f -l ~/logs/boringtun.log wg0
2023-06-29T01:04:31.852309Z ERROR boringtun_cli: Failed to initialize tunnel, error: Socket("Operation not permitted")
at /root/.cargo/registry/src/index.crates.io-6f17d22bba15001f/boringtun-cli-0.5.2/src/main.rs:160

How can I fix it? Or should I let 1stRentalServer to open some functions?
(This VPS seems to be OpenVZ)
(I've let 1st to open "my" VPS's TAP/TUN function)
