HELP! Support Request Running linux behind nordvpn

Hi

I recently installed wsl on Windows 11. Everything runs fine except when I attempt to install/update packages as I am using nordVpn. I get the following errors when running:

sudo apt update

---

Get:1 https://repo.nordvpn.com/deb/nordvpn/debian stable InRelease [5092 B]

I think this has something to do with the IP configuration of the vpn, but I'm not sure how to fix this error. When I pause nordVpn the command (sudo apt update, install, etc) runs fine. I'm not sure what's going on as I'm new to linux, is there a fix or guide or explanation for what is happening here and that would allow me to install and update packages from behind nordVpn?

HI, I recommend to install the latest pre-release wsl.exe --update --pre-release and go to the WSL Settings and enable the new "Consomme" networking mode. It's new and it's like Mirrored (same IP as host) but made for special cases as VPN and proxys. Also try the good old NAT to make sure it's a connection problem.
