Hello, Guix Help!
Sometimes when I connect to vpn with protonvpn-cli and then after some time disconnect
IceCat cannot find sites I have visited before. But it can find new sites perfectly!
Also 'ping gnu.org' gives unknown host, but ping some ip works fine.
This problem goes away when I visit those unawailable web-sites from Chromium with Tor.
I think this is because of DNS cache that protonvpn made in my system.
Can you show me how to flush dns cache after using Protonvpn?

I believe the command you're looking for is 'sudo herd invalidate nscd'

Does this work for you?
--8<---------------cut here---------------start------------->8---
sudo herd invalidate nscd hosts
sudo herd restart nscd
--8<---------------cut here---------------end--------------->8---
