VSCode Github Copilot extension

Repro Steps

Github Copilot extension in VSCode cannot connect

This is my DNS conf:

> cat /etc/resolv.conf
# This file was automatically generated by WSL. To stop automatic generation of this file, add the following entry to /etc/wsl.conf:
# [network]
# generateResolvConf = false
nameserver 10.255.255.254
search home

changing it to resolved my issue

> cat /etc/resolv.conf 
nameserver 1.1.1.1
nameserver 10.255.255.254
search home

> ip addr

I raised this issue because I come from here.
It seems that the default name server 10.255.255.254 has some problems with github copilot domains.

When I connect my same laptop to mobile internet, the issue is resolved.
The problem only occurs when my laptop is connected to a fixed network and using WSL.
Additionally, VSCode on Windows (outside of WSL) on the same laptop does not have any issues with github copilot.

And the problem occurs since 1 or 2 months ago.

Expected Behavior

Github Copilot can connect

Actual Behavior

Github Copilot cannot connect

Facing the same issue. For me, even after adding the nameserver 1.1.1.1, github copilot and few other extension in vs code like gitlens launchpad still does not work. Works perfectly fine on Mobile internet connection or on Windows directly without WSL
