Mullvad is unable to contact system services

Help

I want to use Mullvad (version: 2024.7 ) on my NixOS machine. I installed Mullvad via a devShell flake. And I “deployed” it with nix develop. Here is the flake:

{
  description = "Development environment with Mullvad VPN";

  inputs = {
    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
    flake-utils.url = "github:numtide/flake-utils";
  };

  outputs = { self, nixpkgs, flake-utils }:
    flake-utils.lib.eachDefaultSystem (system:
      let
        pkgs = nixpkgs.legacyPackages.${system};
      in
      {
        devShells.default = pkgs.mkShell {
          packages = with pkgs; [
            mullvad
            mullvad-vpn
          ];

          shellHook = ''
            # You might want to add any initialization here
            echo "Mullvad VPN development environment activated"
          '';
        };
      }
    ) // {
      nixosModules.default = { config, lib, pkgs, ... }: {
        services.mullvad-vpn.enable = true;
      };
    };
}

When trying to use mullvad in the cli I get this error

Error: Management RPC server or client error

Caused by:
    0: transport error
    1: error trying to connect: No such file or directory (os error 2)
    2: No such file or directory (os error 2)

Starting mullvad as gui application show me this:

I also tried to install mullvad in the configuration.nix but I got the same error.

Does anyone know how to fix it?

Thanks in advance!!

I still have not found a way to fix it. Does anyone know the solution?

Assuming this:

I also tried to install mullvad in the configuration.nix but I got the same error.

means you just tried to add it to environment.systemPackages try doing services.mullvad-vpn.enable = true; in your configuration.nix instead.
If it still complains about not being able to connect to system service check its status with systemctl status mullvad-daemon

Thank you sooo much!
