Hi, Thanks for reporting this. I just pushed a new release which updates the dependencies. Try pulling and then rebuilding.

It works. I changed the template file, tried to connect, I get this error messages:

[user@Pinetree ~]$ sudo mlvd connect -p "!(31173|M247|xtom)" "(de|nl|no)-"

That's a wireguard error message, the wireguard kernel module isn't loaded in your kernel. Try loading the kernel module or rebooting.
