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?
