# VPN Troubleshooting Guide #
|
|
|
|
## Tips
|
|
|
|
* If using qubes-vpn, check the VPN service's log in the VPN VM by running:
|
|
~~~
|
|
sudo journalctl -u qubes-vpn-handler
|
|
~~~
|
|
* Always test your basic VPN connection before adding scripts.
|
|
|
|
* Test DNS: Ping a familiar domain name from an appVM. It should print the IP address for the domain.
|
|
|
|
* Use `iptables -L -v` and `iptables -L -v -t nat` to check firewall rules. The latter shows the critical PR-QBS chain that enables DNS forwarding.

## VPN does not reconnect after suspend
|
|
|
|
This applies when using OpenVPN.
|
|
|
|
After suspend/resume, OpenVPN may not automatically reconnect. In order to get it to work, you must kill the OpenVPN process and restart it.
|
|
|
|
## VPN stuck at "Ready to start link"
|
|
|
|
After setting up OpenVPN and restarting the VM, you may be repeatedly getting the popup "Ready to start link", but the VPN isn't connected.
|
|
|
|
To figure out the root of the problem, check the VPN logs in `/var/logs/syslog`. The log may reveal issues like missing OpenVPN libraries, which you can then install.
