VPN Connection not working after setting up autostart

Hello guys,

i’m setting up a VPN VM as a gateway using iptables and cli scripts. I followed this step-by-step guide.

I checked the VPN connection after step 5 (Set up iptables anti-leak rules. Edit the firewall script).
It was working 100%.

After that step I edited the rc.local as written and made it executable.
Then I restart the VPN VM and the connection fails:
Tue Jan 19 19:53:16 2021 RESOLVE: Cannot resolve host address: at.protonvpn.com:1194 (Name or service not known)

I tried to find the logfile - but it is not in the /var/logs/syslog. folder as written in the documentation. Do you know where I can find it?

Im using Qubes 4.0 and the VPN VM is based on Fedora30 - all TemplateVM’s and dom0 are up2date.

I think there is a mistake in the code in rc.local…

Maybe someone has the same mistake?

Thanks in advance for your help!
