Linux tries IPv6 and VPN not working

AmneziaWG and WireGuard protocols do not work properly on Linux

Ordinary programs use IPv6 and hangs. However, sophisticated programs like browsers switches to IPv4 quickly.

wget

real    1m53s   <---- 2 minutes (!) Notice - it tries IPv6

python program - no response

import requests
requests.get("https://ya.ru")

Windows 10 Tries inet6 for 3-5 minutes then switches to inet4 system-wide (windows disables IPv6)

MacOS, Android - no problem (yet)

Fixed client is here. No IPv6 leak has been introduced by this change.

I have a related issue - ipv6 is disabled in the kernel in my OS, and I get the error:

>LOG:1720051188,I,net_addr_v6_add: fd15:53b6:dead::2/64 dev tun0
>LOG:1720051188,W,sitnl_send: rtnl: generic error (-95): Operation not supported
>LOG:1720051188,F,Linux can't add IPv6 to interface tun0

Is it possible to add a setting to disable device ipv6 address insertion?
