Private DNS configuration not working on linux

[technics3]

I am using Netclient 1.5.1 on a Debian 13 host with systemd-resolved and wireguard-tools installed.

I can connect to my Netmaker server fine and talk to every hosts on the VPN, but the DNS configuration on this host is not working.

Hi all, sorry for bumping this up. It impacts our deployment, preventing our client machines from using the internal DNS resolver

Any help apreciated 🙏
