Ethernet and WLAN not working

cn flag

I have Ubuntu 20.04 on my work laptop and today the internet stopped working, although I still see on the network manager that the Ethernet and WLAN networks are still detected. For information, I have Proton VPN and Cisco AnyConnect for my work VPN installed on my system. I often switch between the two.

As I am typing this from another computer, it will be difficult to copy/paste output of commands, but I will do my best

It could be the kill switch from proton vpn, i had this issue a while back and the answer seems to be removing it or just the kill switch: If you run

nmcli device

in the terminal, you can see the available connections and there should be the killswitch listed. By removing it you can use the internet again:

sudo nmcli connection delete pvpn-killswitch
sudo nmcli connection delete pvpn-ipv6leak-protection

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
