Linux tries IPv6 and VPN not working

[alexeyq2]

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)

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?
