1 month ago @RonKhondji Hello! Thank you for your report.
Can you please do adguardvpn-cli config set-debug-logging on, reproduce problem, collect the logs using adguardvpn-cli export-logs and send them to devteam@adguard.com? In title, please specify this issue.

1 month ago Done. The service did start once after turning on the debug logging. After that it kept on failing again.

1 month ago Ok I found something. I'm running my own AdGuardHome dns server and have firewall rules for everything on my local lan to only use that. So 8.8.8.8 and 1.1.1.1 are not accessable from within my lan.
Looking at the logs I think I see adguardvpn-cli trying to connect to 8.8.8.8 instead of using the system dns, so I turned of the firewall rule for a little while. Without that rule the vpn connects fine.
Now I'm just an amateur but it looks like adguardvpn-cli should use the system dns server as the upstream dns and not simply use google or cloudflare.
If I'm wrong, please ignore this :)

1 month ago @RonKhondji Yes, this is DNS related problem.
AG VPN CLI uses both DNS-over-HTTPS and system DNS to resolve its servers. However, when tunnel is already running, it is possible that system DNS loops into AG VPN CLI itself, so DoH is only reliable solution.
We'll look why regular DNS fails during connect in this particular case.
