OpenVpn don't launch on boot

[Sébastien de Pret Roose de Calesberg]

Hi,
I have OpenVpn that work when I launch the command:

openvpn --daemon --script-security 2 --config /etc/openvpn/modal-connector_amsterdam.ovpn

But when I try to have it launch on boot I have the service that launch but I don't have the tun0 showing in ifconfig.

And i did

systemctl enable vpn-start.service

Any idea where the problem could be? Thanks.
(And I ask on the side but is it possible to install zerotier?)

I see that the VPN service is starting so that is a positive. It relies on the voxl-time-sync service to confirm that the date / time is correct before proceeding. One thing to try is to add a sudo to the front of your openvpn call in the service file. Root access may be required depending on your VPN configuration.

I am not familiar with zerotier so can't give you an answer on that one.

It gives me 2021 when I launch the time-sync command, so it should be ok.
Going to try the sudo command.

sudo /usr/sbin/openvpn --daemon --script-security 2 --config /etc/openvpn/modal-connector_amsterdam.ovpn

So something like that in the vpn-start file, right?

@Sébastien-de-Pret-Roose-de-Calesberg Yes, exactly. You may have to specify the whole path of sudo i.e. /usr/bin/sudo

Also, ensure you aren't connecting to your VPN with the same key on a different machine.
